# Lighting

90 cards. Also in the other stage: a shot has a frame too. These decide a frame: what is in it, how it is lit, and what it is made of.

Every card carries what it is, what it does to the audience, where it works best, what to avoid, and the prompt written out in full.

### Name the Source Before the Style

**Also called:** the lighting selector, source before style, what is making this light
**What it is:** The card at the head of the `light.` shelf. It does not describe a look. It asks the three questions the shelf's own pair graph asks over and over — **what is making this light, how much of the subject may go dark, and does the light hold or does it happen** — and hands back a named shortlist for each answer. The axes were not invented: they were read off the fifty-six `Yields to:` conditions the cards carry, and the conditions that repeated became the questions. Every card cited here is cited by id.
**Effect on the audience:** None. This card never reaches the screen. It exists so the card that does reach the screen was chosen against the location, the face and the clock, rather than picked because it was remembered.
**Used for and where it works best:** Answer the three questions **in order and out loud, in one sentence each, before you open the shelf**. The first answer eliminates roughly two-thirds of the file; the second and third leave a shortlist of three to six. If you cannot answer question one — *what is making this light* — you are not ready to light, you are ready to block, and the shot is not designed yet. Where two answers fight for one frame, that is two lighting states and one of them is `light.light_change`.
**Best in:** formats: all | genres: all
**Avoid when:** **You are matching an existing plate, a reference still or a graded frame.** There the light is measured off the picture, not chosen from a shelf, and `light.kelvin_reference` says so in its own `Avoid when:` — *it does not apply when matching real footage, where the number is measured rather than looked up*. Also avoid it on flat 2D, cel or drawn work: axis 1 has no meaning where there is no emitter, and law 5's animation carve-out replaces the question with a palette word. And **distrust axis 1 whenever your honest answer is its third value** — thirty-seven of the seventy-seven cards live there, so on a designed image this map has only two questions left and is doing a third of the work it does on a real location.
**Prompt:** `[Selector — produces no prompt. It returns card ids. The chosen card carries the prompt.]`

---

**The axes**

**Axis 1 — What is making this light, and does the frame have to prove it?**
Asked first, because it is the condition the shelf repeats most: seventeen of the fifty-six `Yields to:` lines turn on justification — *"The room can justify no pattern"* (`light.gobo`), *"No logical source below"* (`light.under`), *"No plausible water"* (`light.caustics`), *"Outside a stage or dream, nothing could make that circle"* (`light.spotlight`), *"No story reason: a real street, not a designed one"* (`light.neon`), *"Commercial, music video or fantasy: image beats justification"* (`light.motivated`), and its exact reverse in `light.dual_colour`.

**Axis 2 — How much of the subject may go dark, and is the dark an amount or a shape?**
Eighteen conditions turn on this and they are stated as facts, not feelings: *"The location must vanish and the dark win"* (`light.chiaroscuro`), *"The scene still needs its geography to read"* (`light.tenebrism`), *"The face needs carving"* (`light.flat`), *"A close-up where patches scramble the features"* (`light.dappled`), *"The figure must read as a type, dress visible"* (`light.silhouette`), *"An emotional dialogue, where the eyes must read"* (`light.top`).

**Axis 3 — Does the light hold, or is the change the shot?**
Eleven conditions are about duration and matching, not look: *"A long scene a real window cannot hold"* (`light.window_soft`), *"A scene too long for twenty minutes"* (`light.magic_hour`), *"The blue is gone, or takes will not match"* (`light.blue_hour`), *"The scene needs softness, or must cut with reverses"* (`light.window_hard`), *"The camera moves, or the room cannot darken"* (`light.vermeer`), *"The green cannot be committed to from shot one"* (`light.fluorescent_green`). It is asked last because it is the only axis that reaches the fourteen event cards at all.

**Axis 2 — how much of the subject may go dark**

| Answer | The shortlist, by id |
| :--- | :--- |
| **None — the light closes every shadow** (21) | `light.three_point` · `light.butterfly` · `light.loop` · `light.flat` · `light.high_key` · `light.soft` · `light.front` · `light.cross` · `light.bounce` · `light.book_light` · `light.window_soft` · `light.golden_hour` · `light.blue_hour` · `light.magic_hour` · `light.sunrise_reveal` · `light.overcast` · `light.open_shade` · `light.blown_out` · `light.hospital_white` · `light.fluorescent_green` · `light.ring_light` |

**Axis 3 — does it hold, or does it happen**

| Answer | The shortlist, by id |
| :--- | :--- |
| **An event — it happens once and the change is the content** (14) | `light.light_change` · `light.reveal_by_light` · `light.eclipse_reveal` · `light.sunrise_reveal` · `light.match_strike` · `light.lightning` · `light.headlight_sweep` · `light.police_sweep` · `light.torch_beam` · `light.lantern_walk` · `light.blinking_neon` · `light.strobe` · `light.concert_beams` · `light.shadow_character` |
| **A state — it must survive a reverse, a second take and an hour** (63) | Every other card named in the two tables above. It is named by complement on purpose: naming sixty-three ids here would make the map longer than the shelf, which is the one thing the template forbids. |

*A card appears once per axis. The answer is the intersection of the three shortlists, and it is normally three to six cards wide.*

---

**The default, and the one against it**

**The default is `light.motivated` governing the room with `light.loop` on the face — and it is measured, not asserted.** `light.loop` is the most-yielded-to card on the shelf: five cards send a reader to it — `light.rembrandt` (*"A short nose, or a light comic scene"*), `light.butterfly` (*"Strong features or a heavy chin"*), `light.split` (*"Natural dialogue, where split shouts at the viewer"*), `light.flat` (*"The scene needs depth, or the face needs carving"*) and `light.front` (*"The scene needs depth; on-axis shadow hits the wall"*). Nothing else on the shelf is named three times except `light.single_source` and `light.backlight_rim`, which are named three times each. The shelf, asked seventy-seven times where to fall back to, falls back here.

**The one against it is `light.shadow_play`.** Nothing routes to it; it is named by no `Yields to:` on the shelf; and it is the only card here where the lit thing is outside the frame and the frame holds only its consequence — a wall. Every other withholding card (`light.silhouette`, `light.hidden_faces`, `light.low_key`, `light.tenebrism`) still puts the body in shot and then takes the face away, which is a subtraction the audience can feel being performed. `light.shadow_play` never makes the promise, so it never breaks it. Its only stated cost is duration — *run too long it tires the viewer because there are no faces and no detail* — which a short beat simply pays. Its near cousin against the grain is `light.under`, which inverts the whole shelf's geometry and is likewise never yielded to by anything.

---

**The unasked**

**Forty-two of the seventy-seven reachable cards are the target of no `Yields to:` field anywhere on this shelf.** They can be chosen but nothing ever sends you to them. By id:

`light.three_point` · `light.kicker` · `light.rembrandt` · `light.butterfly` · `light.low_key` · `light.caravaggio_single_source` · `light.silhouette` · `light.front` · `light.side_raking` · `light.edge` · `light.backlit_halo` · `light.top` · `light.under` · `light.venetian` · `light.available` · `light.window_hard` · `light.vermeer` · `light.smoke` · `light.temple_shaft` · `light.magic_hour` · `light.sunrise_reveal` · `light.overcast` · `light.blown_out` · `light.fluorescent_green` · `light.blinking_neon` · `light.candlelight` · `light.lantern_walk` · `light.match_strike` · `light.torch_beam` · `light.headlight_sweep` · `light.police_sweep` · `light.lightning` · `light.strobe` · `light.phone_glow` · `light.caustics` · `light.spotlight` · `light.concert_beams` · `light.ring_light` · `light.light_change` · `light.reveal_by_light` · `light.shadow_character` · `light.shadow_play`

**And the shape of that list is the finding, not its length.** Every single card under Axis 3's *event* value is on it — all fourteen. `light.match_strike`, `light.lightning`, `light.lantern_walk`, `light.headlight_sweep`, `light.police_sweep`, `light.torch_beam`, `light.light_change`, `light.reveal_by_light`, `light.shadow_character`, `light.eclipse_reveal` (reached only by `light.hidden_faces`), `light.sunrise_reveal`, `light.blinking_neon`, `light.strobe` and `light.concert_beams` **yield outward and nothing yields inward**. The pair graph is a graph of *states*: a reader comparing two looks is comparing two steady conditions, and the fifty-six readers who wrote these fields were each holding one frame, not a scene. **A light that changes on camera is not an alternative to a light that does not — it is a different kind of answer**, and the pair field cannot express it. That is why axis 3 is on this card and why it is asked last rather than not at all.

The second thing the list shows: **the whole hand-held and carried-source region is unasked** — `light.lantern_walk`, `light.torch_beam`, `light.match_strike`, `light.candlelight`, `light.phone_glow`. The shelf treats light as something placed. Nothing on it treats light as something a character is holding and can therefore lose, drop or point at somebody. The new card this shelf wants is the one that says *the source is in the actor's hand and the actor is blocking it* — and the nearest thing that exists, `light.lantern_walk`, records that failure in its own `Avoid when:` (*if the actor swings their arm the light slams into their own face*) without anything routing a reader there to read it.

`light.source_before_style`

### The Colour Temperature Table

**Also called:** the Kelvin reference, the number law 8 asks for, white points  
**What it is:** **The one place in this package where a colour temperature is written as a number.** Law 8 of [`how-to-write-an-image-prompt.md`](how-to-write-an-image-prompt.md) requires every photoreal prompt to declare a Kelvin figure, and until this card existed no craft card supplied one — every lighting card named its source and described the result in words (*warm*, *a relatively cool colour temperature*), so the figure was invented fresh at each prompt. That is how a film acquires colour drift between shots that were all written correctly, and it is the value the keyframe rule at law 8's step 3 forbids altering between a start and end frame: a rule that depended on a number nothing produced.  
**Effect on the audience:** Nothing visible when it is right; when it is wrong the viewer sees two shots of the same room that do not belong to the same afternoon, and reads it as cheapness without being able to say why.  
**Used for and where it works best:** Take the figure from here whenever a photoreal or 3D prompt needs one, and cite this card rather than copying the number into another card — one number, one place, exactly as the safe-zone figures and the reading rate are held. These are the **nominal working values** the trade uses, not measurements of any particular lamp, and a real source drifts with age, dimming and voltage; when a shot is matching real footage, the figure comes from the footage.

| Source | Nominal | Note |
| :--- | :--- | :--- |
| Match, matchstrike | ~1,700 K | the warmest source a scene is likely to contain |
| Candle, candlelight | 1,800-1,900 K | a single candle is also about one stop of usable light |
| Open fire, firelight, hearth, brazier, burning torch | 1,700-2,100 K | flickers in temperature as well as in level; ordinary firelight is never a flash question (`safety.photosensitive_flash` covers only a deliberate strobe or rapid flash sequence) |
| Oil lamp, kerosene lantern, lantern | 1,800-2,000 K | the practical light of every pre-electric interior |
| Sodium vapour, high-pressure sodium, street light | 2,000-2,100 K | the modern orange street; low-pressure sodium is the row further down |
| Incandescent, household bulb, domestic practical | 2,400-2,800 K | domestic tungsten, warmer than a studio lamp |
| Tungsten, studio lamp | 3,200 K | the standard, and the reference every tungsten stock is balanced to |
| Warm-white LED | 2,700-3,000 K | made to imitate the row above; its spectrum is not the same |
| Sunrise, sunset, the sun on the horizon | 2,000-3,000 K | the sun itself, not the sky |
| Golden hour, magic hour | 3,000-4,000 K | the hour after sunrise and before sunset |
| Halogen headlight, car headlight | 3,000-3,500 K | an LED headlight runs 5,000-6,000 K, which is why a modern street looks colder |
| Fluorescent, strip light, hospital and office white | 4,000-4,500 K | the green in it is a separate problem; see the row below |
| Moonlight | ~4,100 K | **it is not blue.** Moonlight is reflected sunlight and reads slightly warm; the blue is a cinematic convention, usually graded to somewhere between 6,500 and 10,000 K |
| Daylight, direct sun, sunlight, noon sun | 5,000-5,600 K | 5,600 K is the reference every daylight stock and every HMI is balanced to. God rays, a dappled floor, a temple shaft and underwater caustics are all this row: what changes is the path, not the source |
| HMI, daylight-balanced fixture | 5,600 K | built to match the row above |
| Available light, natural light, window light | 5,000-6,500 K | take the figure from whichever of the daylight rows the window is actually facing |
| Photographic flash, xenon strobe, strobe | 5,500-6,000 K | |
| Screen, monitor, television, phone, ring light | ~6,500 K | D65 is the standard white point; a phone in night mode shifts far warmer, and a ring light is usually adjustable across this whole range |
| Daylight or cool-white LED | 5,000-6,500 K | |
| Overcast, cloud cover, soft grey daylight | 6,000-7,500 K | |
| Open shade, north-facing window, Vermeer window | 7,000-10,000 K | lit by blue sky rather than by the sun, which is why it is so cool |
| Blue hour, twilight sky | 10,000-12,000 K | the sky itself can measure far higher |
| Lightning | ~20,000 K and up | brief enough that the figure is nominal |
| Low-pressure sodium | **not a colour temperature** | near-monochromatic: it has a colour and no temperature, and nothing lit by it has a true hue |
| Neon, gas-discharge sign | **not a colour temperature** | emits at the lines of whatever gas is in the tube |
| Fluorescent green, the green cast | **not a colour temperature** | a gap in the spectrum, not a temperature - it needs a magenta correction, and it cannot be reached by changing Kelvin |
| Police light, emergency light, stage colour, gelled fixture | **not a colour temperature** | saturated red, blue or a gelled colour is not a white point |

**The last four rows are the part law 8 does not say.** Colour temperature describes a source whose light sits on the blackbody curve, and some of the most recognisable lighting in cinema does not. Where a source is on that list, write its colour in words and give the **ambient** a Kelvin figure instead, because the ambient is what the frame actually balances to.
**Best in:** formats: Feature Film, AI-Generated Clip, Generated Keyframe Feeding Video, Drama Series Episode, Commercial / TVC, Heritage / Historical Documentary, Short Film, Music Video, 3D CG Animation, Portrait Photography, Still Life Photography | genres: all  
**Avoid when:** The work is flat 2D, cel or drawn. There is no emitter in a cel frame to measure, and law 5's animation carve-out replaces the number with the palette temperature in words — writing a Kelvin figure there is a photographic instruction landing on line art. It also does not apply when matching real footage, where the number is measured rather than looked up.  
**Prompt:** `brief: name the motivated source, take its nominal Kelvin from this table, state it once for the scene, and hold it across every shot and both keyframes of a pair`  
**Source:** assumption — the nominal working values the trade uses, as this card says, not traced here to a named publication and not measured from any lamp; a shot matching real footage takes the figure from the footage  
`light.kelvin_reference`

### Three-Point Lighting

**Also called:** key fill and back setup, standard interview setup  
**What it is:** Three sources arranged around the face: a main key from one side, a weaker fill on the opposite side, and a back light that separates the head from the background. It is the skeleton most face lighting is built on.  
**Effect on the audience:** The face reads as a solid three-dimensional shape with depth and the viewer takes in the features without effort. It is legible lighting more than expressive lighting.  
**Used for and where it works best:** Interviews, podcasts, corporate and explainer work: any shot where the face has to land clean and respectable without the lighting stealing attention. In drama use it as a starting point and then break it: kill the fill and the scene turns harsh, kill the back light and the character sticks to the wall and disappears.  
**Best in:** formats: Interview / Video Podcast, Corporate / Training, Explainer, Documentary Feature, News Report / Reportage, Drama Series Episode, Sitcom / Multi-Cam Comedy, Product Video / Motion Design, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Comedy, Science / Educational, Verite / Observational, Medical Drama, Legal Drama, Family  
**Avoid when:** In a realistic scene driven by one real source, a full three-point rig looks manufactured and breaks the truth of the place. In horror and noir it is the enemy of mood because it fills every shadow with light.  
**Prompt:** `classic three point lighting, soft key from camera left, gentle fill on the right, rim light separating the head from the dark background`  
**Yields to:** `light.single_source` — A realistic scene driven by one real source.  
`light.three_point`

### Key Light

**Also called:** main light, principal source  
**What it is:** The strongest and primary source in the shot. It decides where the light comes from and where the shadow falls, and every other light is measured and named relative to it.  
**Effect on the audience:** The angle of the key alone sets the mood of a face: from the side it creates drama, from the front it flattens, from above it sinks the eyes and makes the character unreadable.  
**Used for and where it works best:** The first decision in any scene: where the key sits and which side it comes from. In drama place it around forty five degrees off the lens and slightly above eye height so it reads as natural; in documentary let a window or an existing lamp be the key so the shot stays honest to the room.  
**Best in:** formats: all | genres: all  
**Avoid when:** Do not sit the key on the lens axis unless you want that flatness on purpose. Moving it between two shots in the same scene breaks lighting continuity and the eye feels the mistake even when it cannot name it.  
**Prompt:** `single strong key light from camera left at forty five degrees, slightly above eye level, shaping one side of the face`  
`light.key`

### Fill Light

**Also called:** fill, shadow side light  
**What it is:** A softer source on the opposite side from the key. Its only job is to open the shadow and decide how much of the dark side of the face we are allowed to see.  
**Effect on the audience:** The more fill, the safer and friendlier and more explained the world feels; the less fill, the more secret and threat it carries. Fill is the dial for how much you hide from the viewer.  
**Used for and where it works best:** Raise the fill in comedy, kids content, commercials and interviews so no corner of the face is left in doubt. Bring it down when the character is lying, hiding something, or crossing into a darker stretch of the story, and kill it completely for an interrogation or a confession.  
**Best in:** formats: Feature Film, Drama Series Episode, Interview / Video Podcast, Commercial / TVC, Kids Content, Corporate / Training, Documentary Feature, Anime (Japanese 2D), Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Comedy, Thriller / Suspense, Noir / Neo-Noir, Crime / Procedural, Family, Preschool / Early Learning, Psychological / Arthouse  
**Avoid when:** A fill stronger than the key inverts the setup and leaves the face flat with no direction. In a night scene too much fill kills the night and makes the location look lit from every side for no reason.  
**Prompt:** `strong key from the left with almost no fill on the right, the shadow side of the face falling into near black`  
`light.fill`

### Lighting Ratio / Key to Fill Ratio

**Also called:** contrast ratio, key-fill ratio  
**What it is:** The numerical relationship between the intensity of the key and the intensity of the fill. A ratio of one to one gives a flat face with no shadow side; eight to one gives one bright side and one nearly black side.  
**Effect on the audience:** The ratio decides how harsh or how merciful a scene feels before colour or movement enter the picture at all. The viewer reads it as a level of safety.  
**Used for and where it works best:** Let the ratio travel with the story inside one piece: two to one in the opening act, eight to one for the collapse. In series and drama it is the easiest way to make an episode feel like it is heading somewhere without changing a single camera or colour choice.  
**Best in:** formats: Feature Film, Drama Series Episode, Limited Series, Short Film, Commercial / TVC, Documentary Feature, Anime (Japanese 2D), 3D CG Animation, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Thriller / Suspense, Noir / Neo-Noir, Crime / Procedural, Horror, Romance, Historical / Biopic, Tragedy  
**Avoid when:** Do not let the ratio swing without intent between shots in the same scene, because it reads as an error and not as a style. In a commercial built on faces a high ratio makes the product feel dangerous.  
**Prompt:** `high contrast lighting ratio, bright key side and deep unfilled shadow side, hard falloff across the face`  
`light.ratio`

### Back Light / Rim Light

**Also called:** rim, edge light, separation light  
**What it is:** A source placed behind the subject facing the camera, drawing a line of light along the edge of the head and shoulders. Usually it sits above head height and slightly off to one side.  
**Effect on the audience:** It lifts the subject off the background and brings them back out of the dark. The result is heroic and attractive: a line of light drawing the outline of the body inside the blackness.  
**Used for and where it works best:** Any night scene or dark background, otherwise the subject melts into the wall. In heritage and epic work it is the light that makes a figure on a rampart or walking through a temple gate look monumental, and in battle anime it announces that the person entering is the hero.  
**Best in:** formats: Feature Film, Drama Series Episode, Trailer / Teaser, Heritage / Historical Documentary, Anime (Japanese 2D), Music Video, Commercial / TVC, Game Cinematic / Gameplay, 3D CG Animation, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Action, Fantasy / Epic, Mythology / Ancient Epic, Heritage (civilisation-focused), Noir / Neo-Noir, Thriller / Suspense, Shonen Battle (anime), Historical / Biopic, War  
**Avoid when:** A back light against a bright background does nothing because there is nothing for it to separate from. Pushed too hard it becomes an advertising halo that breaks the realism of a poor or brutal scene.  
**Prompt:** `strong rim light from behind and above, a bright edge tracing the shoulders and hair against a dark background`  
`light.backlight_rim`

### Kicker / Three-Quarter Back Light

**Also called:** kick light, back cross key  
**What it is:** An angled source behind and to the side of the subject at three quarters, catching the cheekbone and jaw on the shadow side. It differs from a plain back light in that it paints a plane rather than a thin line.  
**Effect on the audience:** It gives the face structure and sculpting without lifting the overall exposure. The character looks stronger, harder and sharper in the bone.  
**Used for and where it works best:** A close-up of a hero or a villain in a night scene, and in cinematic portraiture when you want the jaw and the bone to show. It is excellent in trailers and in perfume or car commercials because it sculpts the face without giving up the darkness.  
**Best in:** formats: Feature Film, Trailer / Teaser, Commercial / TVC, Music Video, Drama Series Episode, Fashion Film, Game Cinematic / Gameplay, Anime (Japanese 2D), Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Noir / Neo-Noir, Crime / Procedural, Thriller / Suspense, Action, Gangster, Spy / Espionage, Superhero, Seinen (mature anime)  
**Avoid when:** On a soft face or textured skin a kicker exposes every pore and blemish. In a documentary interview it looks staged and suggests the subject was dressed for camera rather than caught as they are.  
**Prompt:** `hard kicker from behind camera right at three quarters, carving the cheekbone and jawline out of the shadow side`  
**Yields to:** `light.backlight_rim` — Soft or textured skin: a line, not a plane.  
`light.kicker`

### Hair Light

**Also called:** top back light, halo light  
**What it is:** A narrow source from above and behind aimed only at the hair, not the face and not the shoulders. It is usually smaller and more controlled than a general back light.  
**Effect on the audience:** The hair regains texture and shine instead of reading as one black mass, and the head frees itself from the background. The feeling is clean and polished.  
**Used for and where it works best:** Any character with dark hair against a dark background, especially in interviews, commercials, fashion and music performance. In period drama it is what lets a braid or a head cloth show its detail instead of dissolving into the dark.  
**Best in:** formats: Interview / Video Podcast, Commercial / TVC, Fashion Film, Music Video, Drama Series Episode, Product Video / Motion Design, Corporate / Training, Wedding / Event Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Romance, Drama, Musical, Family, Historical / Biopic, Heritage (civilisation-focused), Melodrama  
**Avoid when:** Pushed too hard it puts a white ring on top of the head that looks cheap and dated. In a grimy or poor scene it is the first light to remove, because it makes the character look styled.  
**Prompt:** `small controlled hair light from above and behind, adding shine and texture to the top of the hair only`  
`light.hair_light`

### Background Light / Set Light

**Also called:** kicker on the set, wall light, separation on the background  
**What it is:** An independent source aimed at the background itself rather than the subject: a wall, a curtain, a street or the depth of a room. It decides how much of the world behind the character exists.  
**Effect on the audience:** It creates depth. A partially lit background gives layers and a real place; a completely black background leaves the character suspended in nowhere.  
**Used for and where it works best:** Any interior where you want the place to read as a real place and not a studio. In documentary put a soft gradient on the wall behind the speaker so the frame feels designed without stealing the face, and in heritage work light the carved relief behind the speaker so the location argues for the subject.  
**Best in:** formats: Interview / Video Podcast, Documentary Feature, Heritage / Historical Documentary, Corporate / Training, Drama Series Episode, Sitcom / Multi-Cam Comedy, Explainer, News Report / Reportage, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Verite / Observational, Science / Educational, Historical / Biopic, Heritage (civilisation-focused), Drama, Legal Drama, Medical Drama, True Crime  
**Avoid when:** If the background light is stronger than the face, the eye leaves the person and goes to the wall. A visible round hot spot on the wall right behind the head looks dated and cheap.  
**Prompt:** `soft gradient of light on the back wall behind the subject, darker at the edges, giving depth without pulling focus`  
`light.background_light`

### Eye Light / Catchlight

**Also called:** catch light, obie light  
**What it is:** A small weak source close to the camera whose only job is to leave a bright point inside the pupil. It does not raise the exposure of the face; it only makes the eye live.  
**Effect on the audience:** The difference between a face with a person inside it and a dead face. That point of light in the eye is what makes the viewer feel the character is thinking.  
**Used for and where it works best:** Every emotional close-up: the confession, the held-back tears, the moment of love or decision. And the reverse, remove it on purpose when you want the character to feel empty, possessed or not quite human, which is a standard horror move.  
**Best in:** formats: Feature Film, Drama Series Episode, Commercial / TVC, Music Video, Interview / Video Podcast, Anime (Japanese 2D), 3D CG Animation, Fashion Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Romance, Horror, Thriller / Suspense, Melodrama, Psychological / Arthouse, Supernatural Horror, Shojo (anime romance)  
**Avoid when:** Two visible catchlights in each eye means two sources sitting close together and reads as a technical error. In a scene that is supposed to be pitch dark, a catchlight exposes a light source the story never justified.  
**Prompt:** `a small clean catchlight in both eyes, the rest of the face lit low, the eyes alive inside the shadow`  
`light.eye_light`

### Rembrandt Lighting

**Also called:** forty five degree lighting, triangle lighting  
**What it is:** A key at forty five degrees to the side and above eye height, so the nose casts a shadow that drops and meets the cheek shadow, leaving a small triangle of light under the eye on the dark side. Named after the painter Rembrandt.  
**Effect on the audience:** Gravity, dignity and inner depth. The face divides between light and shadow without losing either, so the character reads as having two layers.  
**Used for and where it works best:** Serious dramatic dialogue, cinematic portraiture, the shot of a character weighing a hard decision. In historical and heritage documentary it is the lighting of the elder and the narrator, and in a deep interview it gives the subject weight without hiding them.  
**Best in:** formats: Feature Film, Drama Series Episode, Interview / Video Podcast, Heritage / Historical Documentary, Documentary Feature, Short Film, Anime (Japanese 2D), Fashion Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Historical / Biopic, Heritage (civilisation-focused), Tragedy, Noir / Neo-Noir, Faith / Biblical Epic, Mystery / Whodunit, Seinen (mature anime)  
**Avoid when:** On a short nose or from the wrong angle the triangle becomes a blob and the whole pattern collapses. In a light or comic scene it feels heavy and pretentious.  
**Prompt:** `Rembrandt lighting, key at forty five degrees above eye level, small triangle of light on the shadow side cheek under the eye`  
**Yields to:** `light.loop` — A short nose, or a light comic scene.  
`light.rembrandt`

### Butterfly Lighting / Paramount Lighting

**Also called:** glamour lighting, beauty light  
**What it is:** A key placed directly in front and high above the face, leaving a small symmetrical shadow under the nose shaped like a butterfly. It usually comes with a reflector under the chin.  
**Effect on the audience:** Glamour. The cheekbones carve, the eyes light up and the skin smooths. The face becomes an icon rather than an ordinary person.  
**Used for and where it works best:** The star shot, luxury commercials, music performance, the cover image. In a feature use it for a single moment when you want the viewer to see the character through the eyes of the person in love with them, not for the whole film.  
**Best in:** formats: Commercial / TVC, Fashion Film, Music Video, Product Video / Motion Design, Drama Series Episode, Feature Film, Wedding / Event Film, Concert / Live Event, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Romance, Musical, Melodrama, Drama, Comedy, Rom-Com, Family  
**Avoid when:** On strong features or a heavy chin the shadow under the nose becomes an ugly black line. In a realistic or poor scene it reads as an obvious lie.  
**Prompt:** `butterfly lighting, soft key directly above and in front of the face, small symmetrical shadow under the nose, reflector filling the chin`  
**Yields to:** `light.loop` — Strong features or a heavy chin.  
`light.butterfly`

### Loop Lighting

**Also called:** loop pattern, the standard portrait key  
**What it is:** The key at a narrower angle than Rembrandt, around thirty degrees, slightly above eye height, so the nose shadow drops at an angle but never reaches the cheek shadow and stays as a small separate loop.  
**Effect on the audience:** The best balance between natural and sculpted. The face has a clear direction and a gentle shadow without any extra drama.  
**Used for and where it works best:** The default face lighting for most drama, interview and commercial work because it flatters almost every face shape. Start here and then move the source: bring it toward the lens and you get flat light, push it further round and you get Rembrandt and then split.  
**Best in:** formats: all | genres: Drama, Romance, Comedy, Family, Verite / Observational, Science / Educational, Historical / Biopic, Slice of Life  
**Avoid when:** It does not deliver strong drama, so if the scene needs threat or secrecy it is too mild to carry meaning. Set it too high and the nose shadow drops onto the lip and reads as a mistake.  
**Prompt:** `loop lighting, key thirty degrees off axis and slightly above eye level, small nose shadow curving down but not touching the cheek shadow`  
**Yields to:** `light.split` — The scene needs threat or secrecy.  
`light.loop`

### Split Lighting

**Also called:** side light portrait, half and half  
**What it is:** The key at a full ninety degrees to the side of the face, so one half is lit and the other is in shadow with the line running down the middle of the nose. The purest form of side light on a face.  
**Effect on the audience:** Internal division. The viewer instantly reads a character with two faces: truth and lie, good and evil, past and present.  
**Used for and where it works best:** The moment a character's duality is exposed, or the confession and interrogation scene. In noir, crime and psychological thriller it is the signature of the divided self, and in heritage work it half hides a face in a way that suggests secrecy without removing the person.  
**Best in:** formats: Feature Film, Drama Series Episode, Trailer / Teaser, Short Film, Anime (Japanese 2D), Music Video, Game Cinematic / Gameplay, Heritage / Historical Documentary, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Noir / Neo-Noir, Crime / Procedural, Thriller / Suspense, Psychological / Arthouse, Psychological Horror, Mystery / Whodunit, Drama, Tragedy, Seinen (mature anime)  
**Avoid when:** Used on every shot of a scene it loses its meaning and becomes decoration. In natural dialogue it makes the viewer feel the director is shouting at them.  
**Prompt:** `split lighting, hard key at ninety degrees from the side, one half of the face lit and the other half falling into black`  
**Yields to:** `light.loop` — Natural dialogue, where split shouts at the viewer.  
`light.split`

### Broad Lighting

**Also called:** broad side key  
**What it is:** The face is turned to one side and the key lights the side closest to camera, meaning the broader visible side of the face is the lit one. The opposite of short lighting.  
**Effect on the audience:** The face looks wider, fuller and more open. The feeling is friendly, direct and without secrets.  
**Used for and where it works best:** Good for thin faces you want to fill out, and for warm open characters in comedy, sitcom and kids content. In an interview use it when you want the guest to look relaxed and welcoming.  
**Best in:** formats: Sitcom / Multi-Cam Comedy, Kids Content, Interview / Video Podcast, Corporate / Training, Commercial / TVC, Drama Series Episode, 2D Animation (Western / Cartoon), Vlog / YouTube Long-Form, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Comedy, Family, Preschool / Early Learning, Rom-Com, Slice of Life, Science / Educational, Verite / Observational  
**Avoid when:** On an already wide face it makes it wider and heavier. In a serious dramatic scene it flattens the character and removes the mystery the scene needs.  
**Prompt:** `broad lighting, subject turned away from the key, the near side of the face fully lit and open`  
**Yields to:** `light.short` — An already wide face, or a serious dramatic scene.  
`light.broad`

### Short Lighting

**Also called:** narrow lighting, short side key  
**What it is:** The face is turned to one side and the key lights the far side from camera, so the narrow side is lit and the broader side falls into shadow.  
**Effect on the audience:** The face looks slimmer, more sculpted and deeper. The feeling is serious and something is being withheld.  
**Used for and where it works best:** Serious cinematic portraiture and the shot of a strong or guarded character in drama and crime. It is the default when you want to sculpt a face, and in interviews it gives the subject authority and weight.  
**Best in:** formats: Feature Film, Drama Series Episode, Interview / Video Podcast, Fashion Film, Trailer / Teaser, Heritage / Historical Documentary, Music Video, Short Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Crime / Procedural, Noir / Neo-Noir, Thriller / Suspense, Historical / Biopic, Heritage (civilisation-focused), Tragedy, Mystery / Whodunit  
**Avoid when:** On an already thin face it can look gaunt or unwell unless that is exactly the intention. In kids content and comedy it makes the character read cold and distant.  
**Prompt:** `short lighting, subject turned toward the key, the near side of the face in shadow and the far narrow side lit`  
**Yields to:** `light.broad` — An already thin face, kids content or comedy.  
`light.short`

### Flat Lighting / Beauty Lighting

**Also called:** on-axis light, frontal soft light  
**What it is:** A large soft source sitting almost on the lens axis, hitting the face head on so almost no shadow survives. Usually a big softbox above the camera with a reflector underneath.  
**Effect on the audience:** The skin smooths, the lines disappear and the face loses depth. The feeling is clean and safe, and at the same time without secret or threat.  
**Used for and where it works best:** Beauty commercials, product video, kids content, and the vlog or reel where the job is a clear friendly face. In drama use it deliberately when you want a character to feel artificial, staged or too perfect to be true.  
**Best in:** formats: Commercial / TVC, Product Video / Motion Design, Kids Content, Vlog / YouTube Long-Form, Vertical Short-Form (Reels, Shorts, TikTok), Corporate / Training, Explainer, Fashion Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Comedy, Family, Preschool / Early Learning, Rom-Com, Science / Educational, Musical, Surreal / Absurdist  
**Avoid when:** In any scene that needs depth, threat or truth, flat lighting kills it. On a large face it makes it read wider because there is no shadow to carve it.  
**Prompt:** `flat beauty lighting, very large soft source on the lens axis, no visible shadows, smooth even skin`  
**Yields to:** `light.loop` — The scene needs depth, or the face needs carving.  
`light.flat`

### High Key Lighting

**Also called:** high-key, bright scheme  
**What it is:** A high overall light level with very few shadows and a small gap between bright and dark. It is not just a bright face; it is a whole scene built on brightness.  
**Effect on the audience:** Safety, optimism and cleanliness. The viewer feels nothing is hidden in the frame, drops their guard and relaxes.  
**Used for and where it works best:** Comedy, sitcom, kids content, commercials and explainers, anything that has to feel friendly and easy. In thrillers use it as irony: horror inside a white hospital or a sunlit house lands harder than horror in the dark.  
**Best in:** formats: Sitcom / Multi-Cam Comedy, Kids Content, Commercial / TVC, Explainer, Corporate / Training, Product Video / Motion Design, 2D Animation (Western / Cartoon), Vertical Short-Form (Reels, Shorts, TikTok), Drama Series Episode, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Comedy, Family, Preschool / Early Learning, Rom-Com, Musical, Science / Educational, Fairy Tale, Surreal / Absurdist  
**Avoid when:** In heavy drama it makes the scene feel weightless. Used in a night scene with no justification it exposes the location as a studio.  
**Prompt:** `high key lighting, bright even exposure, soft shadows barely visible, clean airy white environment`  
**Yields to:** `light.hospital_white` — Same brightness, when it must be cruel not safe.  
`light.high_key`

### Low Key Lighting

**Also called:** low-key, dark scheme  
**What it is:** A low overall light level where shadow governs the frame, built from few directed sources. The black is part of the composition, not a shortfall of exposure.  
**Effect on the audience:** Danger, mystery and tension. The viewer searches the darkness with their eyes and expects something to come out of it.  
**Used for and where it works best:** Horror, noir, crime and thriller, and any scene of night, secrecy or threat. In heritage work use it inside a temple or a palace at night so the architecture feels larger than the human standing in it.  
**Best in:** formats: Feature Film, Drama Series Episode, Trailer / Teaser, Short Film, Anime (Japanese 2D), Game Cinematic / Gameplay, Heritage / Historical Documentary, Music Video, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Horror, Noir / Neo-Noir, Crime / Procedural, Thriller / Suspense, Mystery / Whodunit, Psychological Horror, Gothic / Vampire, War, Supernatural Horror  
**Avoid when:** Pushed so low that we never see the character at all, it turns from mystery into frustration. On small screens and in vertical feeds deep darkness is simply lost in daylight viewing on a phone.  
**Prompt:** `low key lighting, one directed source, deep black shadows filling most of the frame, only the essential shapes visible`  
**Yields to:** `light.practicals` — Small screens and vertical, where darkness is lost.  
`light.low_key`

### Chiaroscuro

**Also called:** light dark modelling  
**What it is:** A very hard contrast between a lit area and a black area, so form is built from that collision rather than from gradation. The term comes from Italian painting.  
**Effect on the audience:** The image becomes a painting. The viewer feels a moral weight: there is light and there is darkness and the character stands between them.  
**Used for and where it works best:** A religious or moral scene, the confession, a character inside a church, a temple or a cell. In heritage documentary it works beautifully on artefacts and statues because it carves them the way a torch would have shown them.  
**Best in:** formats: Feature Film, Heritage / Historical Documentary, Short Film, Anime (Japanese 2D), Trailer / Teaser, Documentary Feature, Experimental / Art Film, Game Cinematic / Gameplay, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Noir / Neo-Noir, Faith / Biblical Epic, Historical / Biopic, Heritage (civilisation-focused), Mythology / Ancient Epic, Gothic / Vampire, Tragedy, Psychological / Arthouse  
**Avoid when:** In an ordinary everyday scene it looks mannered and theatrical. Applied to every scene it tires the eye and loses its force.  
**Prompt:** `chiaroscuro lighting, one hard source carving the subject out of deep blackness, sharp boundary between light and dark`  
**Example:** The paintings of Caravaggio, where a single directional light lifts the figures out of a black ground.  
**Yields to:** `light.tenebrism` — The location must vanish and the dark win.  
`light.chiaroscuro`

### Tenebrism

**Also called:** dramatic darkness, spotlit darkness  
**What it is:** A more extreme relative of chiaroscuro: darkness is the ground and light is a small intruder on it, with a background that is pure black and carries no detail at all. The difference is that chiaroscuro balances light against dark while tenebrism lets the dark win.  
**Effect on the audience:** Total isolation and a sacred kind of fear. The subject appears severed from any location, suspended in nothing.  
**Used for and where it works best:** The face shot in a trailer, the character after a great loss, the scene where you want the location to vanish and leave only the human being. In heritage and myth it suits a statue or a cuneiform tablet isolated in blackness so it becomes an icon.  
**Best in:** formats: Trailer / Teaser, Feature Film, Heritage / Historical Documentary, Experimental / Art Film, Music Video, Title Sequence / Opening Credits, Anime (Japanese 2D), AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Tragedy, Horror, Gothic / Vampire, Faith / Biblical Epic, Mythology / Ancient Epic, Heritage (civilisation-focused), Psychological / Arthouse, Drama  
**Avoid when:** It needs a genuinely black background, so in any space with spill it fails and simply looks underlit. In scenes that need geography it erases the very location you need.  
**Prompt:** `tenebrism, subject emerging from total blackness, a single small light source, background with no detail at all`  
**Yields to:** `light.chiaroscuro` — The scene still needs its geography to read.  
`light.tenebrism`

### Caravaggio Single-Source Look

**Also called:** painterly single source, raking single key  
**What it is:** One hard source entering from high and to the side at a steep angle, with no fill and no back light, and the background left black. The face and the hands emerge from the dark while everything else is erased. Named after the painter Caravaggio.  
**Effect on the audience:** An immediate religious drama. The light reads as a decision from above rather than a lamp, so the moment carries more meaning than its size.  
**Used for and where it works best:** A scene of revelation, repentance or betrayal around a table, and any moment where a hand reaches out and takes something. In heritage work it is the best light for a scribe at his tablet or a priest at an altar, because it evokes an age that only ever had one source.  
**Best in:** formats: Feature Film, Heritage / Historical Documentary, Short Film, Docudrama / Reenactment, Trailer / Teaser, Anime (Japanese 2D), 3D CG Animation, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Faith / Biblical Epic, Historical / Biopic, Heritage (civilisation-focused), Mythology / Ancient Epic, Drama, Tragedy, Gothic / Vampire, Noir / Neo-Noir  
**Avoid when:** It needs full control of spill, so in a room with pale walls the bounce destroys the effect. Do not use it in a daylight exterior because it becomes an obvious lie.  
**Prompt:** `single hard light entering from high camera left at a steep angle, no fill, black background, hands and face lifted out of darkness`  
**Yields to:** `light.single_source` — Pale walls, where the bounce cannot be controlled.  
`light.caravaggio_single_source`

### Silhouette Lighting

**Also called:** backlit silhouette, blacked-out subject  
**What it is:** All the light sits behind the subject and the background is bright while the subject gets no frontal light at all, so the figure reads as a black shape with a clean outline.  
**Effect on the audience:** Identity is erased and only shape and posture survive. The viewer paints in the face they never saw, so the figure becomes a symbol rather than a specific person.  
**Used for and where it works best:** Openings, endings and the departure shot, and the scene of an unknown or threatening figure. In heritage documentary it is the core device for showing people without showing faces, and in commercials and music video it gives a clean icon that reads at any screen size.  
**Best in:** formats: Heritage / Historical Documentary, Feature Film, Music Video, Trailer / Teaser, Title Sequence / Opening Credits, Commercial / TVC, Vertical Short-Form (Reels, Shorts, TikTok), Anime (Japanese 2D), AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Heritage (civilisation-focused), Mythology / Ancient Epic, Historical / Biopic, Drama, Thriller / Suspense, War, Noir / Neo-Noir, Mystery / Whodunit, Faith / Biblical Epic  
**Avoid when:** If the shape does not read cleanly, with a limb lost or an ambiguous pose, the shot becomes a puzzle instead of a statement. Repeated too often in one piece it starts to feel like you are hiding a production problem.  
**Prompt:** `full silhouette, bright window behind the figure, no frontal light at all, the body reading as a clean black shape`  
**Yields to:** `light.hidden_faces` — The figure must read as a type, dress visible.  
`light.silhouette`

### Hard Light

**Also called:** hard source, sharp shadow light  
**What it is:** Light from a source that is small relative to the subject, throwing a shadow with a sharp edge and a fast transition from lit to dark. Open sun and a bare lamp are the models.  
**Effect on the audience:** Harshness, truth and threat. Texture comes forward, pores, lines and dust all show, and the image feels merciless.  
**Used for and where it works best:** Desert, hard sun, interrogation, prison and war: anywhere the world is not supposed to be comfortable. On surfaces and artefacts it is what makes stone and carving read as genuinely cut rather than printed.  
**Best in:** formats: Feature Film, Drama Series Episode, Heritage / Historical Documentary, Documentary Feature, Short Film, Trailer / Teaser, Game Cinematic / Gameplay, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: War, Western, Thriller / Suspense, Crime / Procedural, Survival, Historical / Biopic, Heritage (civilisation-focused), Noir / Neo-Noir, Dystopia / Post-Apocalyptic  
**Avoid when:** On faces in a romance scene or a beauty commercial it exposes every flaw and breaks the mood. With several hard sources at once the shadows cross each other and the frame turns into noise.  
**Prompt:** `hard direct light, sharp edged shadows, strong texture on the skin and the stone surfaces`  
**Yields to:** `light.soft` — Faces in romance or beauty work.  
`light.hard`

### Soft Light

**Also called:** soft source, diffused light  
**What it is:** Light from a source that is large relative to the subject, or passed through diffusion, or bounced off a wide surface, so the shadow edge becomes a gradual soft transition.  
**Effect on the audience:** Gentleness, safety and beauty. The skin smooths, the mood settles and the image feels kind to the character.  
**Used for and where it works best:** Romance, family, childhood and warm memory, and the interview where you want the guest at ease. In heritage work use it inside a house or a workshop by day so the place feels inhabited rather than shot.  
**Best in:** formats: Feature Film, Drama Series Episode, Interview / Video Podcast, Commercial / TVC, Kids Content, Wedding / Event Film, Fashion Film, Documentary Feature, Music Video, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Romance, Family, Drama, Melodrama, Preschool / Early Learning, Rom-Com, Slice of Life, Historical / Biopic  
**Avoid when:** Softness everywhere leaves a scene weightless and without threat, and in horror or noir it is the fastest way to kill tension. In a hard sun exterior, pretending to softness simply reads as a lie.  
**Prompt:** `large soft source through diffusion, gentle shadow falloff, smooth even light on the skin`  
**Yields to:** `light.hard` — Horror, noir, or a hard sun exterior.  
`light.soft`

### Front Light / Frontal Lighting

**Also called:** on-axis lighting, flat-on light  
**What it is:** The source sits on roughly the same axis as the camera, so the shadow falls behind the subject where we cannot see it. It differs from beauty lighting in that it can be hard rather than soft.  
**Effect on the audience:** Complete clarity with no depth. The subject looks exposed and declared with no secret, and in the hard version they look caught and pinned.  
**Used for and where it works best:** News reporting, explainer and direct response commercials where instant clarity is the whole job. In drama use it for a scene of exposure or investigation: a hard frontal source catches the character and leaves them nowhere to hide.  
**Best in:** formats: News Report / Reportage, Explainer, Commercial / TVC, Corporate / Training, Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Drama Series Episode, Meme / Comedy Edit, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Science / Educational, Comedy, Thriller / Suspense, Crime / Procedural, Legal Drama, Drama, True Crime, Surreal / Absurdist  
**Avoid when:** In a scene that needs depth and mood it removes every trace of the third dimension. In the hard version it throws a shadow on the wall directly behind the head, which is the worst look in all of lighting.  
**Prompt:** `frontal light on the camera axis, no visible shadow on the face, the subject fully exposed and readable`  
**Yields to:** `light.loop` — The scene needs depth; on-axis shadow hits the wall.  
`light.front`

### Side Light / Raking Light

**Also called:** raking light, ninety degree side light, texture light  
**What it is:** Light arriving from the side at close to ninety degrees and skimming almost parallel to the surface, so every bump and hollow throws its own small shadow.  
**Effect on the audience:** Texture explodes. A wall becomes stone, skin becomes skin, and a carving becomes truly cut. On a face it gives division and tension.  
**Used for and where it works best:** It is the first choice for shooting any artefact: cuneiform, relief, wall, woven cloth. In commercials it reveals the texture of a product, and in drama on a face beside a window it gives you half a truth.  
**Best in:** formats: Heritage / Historical Documentary, Documentary Feature, Product Video / Motion Design, Commercial / TVC, Feature Film, Drama Series Episode, Fashion Film, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Heritage (civilisation-focused), Historical / Biopic, Drama, Noir / Neo-Noir, Thriller / Suspense, Science / Educational, Nature / Wildlife, Mythology / Ancient Epic  
**Avoid when:** On a face with texture you did not want to show, it exposes it without mercy. If the surface is already smooth you gain nothing and lose clarity of information.  
**Prompt:** `raking side light skimming across the carved stone surface, every groove throwing its own small shadow`  
**Yields to:** `light.soft` — Texture on a face you do not want shown.  
`light.side_raking`

### Edge Lighting

**Also called:** contour light, double edge light, dual rim  
**What it is:** A very thin hard line of light drawing the outline of the shape, often from both sides, with the interior left dark. It differs from a back light in being thinner and harder and intended as a drawn line rather than as separation.  
**Effect on the audience:** The shape turns into a drawing, and the figure reads as powerful and detail free. The feeling is heroic and designed.  
**Used for and where it works best:** The entrance shot in a trailer, in battle anime and in game cinematics, and the title card. In music video it delivers a clean shape on black, and in sports commercials it draws the athlete as an icon before the action starts.  
**Best in:** formats: Trailer / Teaser, Anime (Japanese 2D), Game Cinematic / Gameplay, 3D CG Animation, Music Video, Title Sequence / Opening Credits, Commercial / TVC, Sports Broadcast / Sports Film, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Action, Shonen Battle (anime), Superhero, Mecha (anime), Sci-Fi, Fantasy / Epic, Cyberpunk, Sports Drama  
**Avoid when:** In a realistic scene two symmetrical light lines have no source in the room and look manufactured. Over a long dialogue it becomes decoration that blocks any reading of the performance.  
**Prompt:** `thin hard dual edge lights outlining both sides of the figure, the interior left in shadow, black background`  
**Yields to:** `light.backlight_rim` — A realistic room or a long dialogue.  
`light.edge`

### Backlit Halo / Sun Halo

**Also called:** halation backlight, hero halo, glow backlight  
**What it is:** A strong source directly behind the head close to the lens axis, with a little haze or dust, so the hair and shoulders gather a spreading glow rather than a clean line.  
**Effect on the audience:** Sanctity and nostalgia. The figure looks as if they come from a memory or from another world, and the image feels warm rather than sharp.  
**Used for and where it works best:** Flashback, childhood, the appearance of a mother or a lover, and the final shot into a low sun. In heritage and faith work it gives the figure the feel of legend, and in family advertising it delivers instant warmth without a word.  
**Best in:** formats: Feature Film, Commercial / TVC, Music Video, Heritage / Historical Documentary, Wedding / Event Film, Drama Series Episode, Short Film, Kids Content, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Romance, Family, Faith / Biblical Epic, Heritage (civilisation-focused), Drama, Melodrama, Fairy Tale, Coming of Age  
**Avoid when:** Blown too far the halo eats the face and leaves a white fog with no information. In a brutal or criminal scene it lends a sentiment the story never earned.  
**Prompt:** `strong low sun directly behind the subject with light haze, a soft glowing halo around the hair and shoulders, warm flare edges`  
**Yields to:** `light.backlight_rim` — A brutal or criminal scene, sentiment unearned.  
`light.backlit_halo`

### Top Light / Overhead Light

**Also called:** toplight, downlight  
**What it is:** A source directly overhead pointing straight down, so the forehead, nose and shoulders catch the light while the eyes sink into shadow.  
**Effect on the audience:** The character becomes unreadable. You cannot tell what they are thinking because the eyes are hidden, so they carry danger, isolation or a cold authority.  
**Used for and where it works best:** The crime boss at his table, the character who has just made a bad decision, and any scene under a street lamp or a warehouse fixture. In heritage documentary it gives a statue or a carved face the feel of a temple lit from a roof opening.  
**Best in:** formats: Feature Film, Drama Series Episode, Trailer / Teaser, Heritage / Historical Documentary, Anime (Japanese 2D), Game Cinematic / Gameplay, Music Video, Short Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Gangster, Crime / Procedural, Noir / Neo-Noir, Thriller / Suspense, Horror, Psychological / Arthouse, Mythology / Ancient Epic, Heritage (civilisation-focused), Seinen (mature anime)  
**Avoid when:** In an emotional dialogue with no reason for it, the eyes die and the entire performance is lost. On an older face it deepens the eye sockets and makes the person look ill.  
**Prompt:** `hard overhead top light straight down, the eyes falling into deep shadow, bright forehead and shoulders`  
**Example:** The Godfather (1972), Gordon Willis keeping the eyes of Don Corleone in shadow under overhead light.  
**Yields to:** `light.eye_light` — An emotional dialogue, where the eyes must read.  
`light.top`

### Under-Lighting / Uplighting

**Also called:** horror light, campfire light, monster light  
**What it is:** A source below the chin aiming upward, so the shadows invert: the nose shadow climbs the forehead and the brows throw a shape the face never normally has.  
**Effect on the audience:** Instant wrongness. The human brain has never learned to see a face lit this way, so it reads the character as a threat, a liar or something not quite human.  
**Used for and where it works best:** The moment a monster or a broken character is revealed, the ghost story around a fire, and the figure staring down at a screen or a candle on the floor. In dark comedy it works as a deliberate exaggeration when introducing the villain.  
**Best in:** formats: Feature Film, Short Film, Anime (Japanese 2D), Trailer / Teaser, Game Cinematic / Gameplay, Vertical Short-Form (Reels, Shorts, TikTok), Music Video, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Horror, Supernatural Horror, Slasher, Gothic / Vampire, Psychological Horror, Dark Comedy / Satire, Monster / Kaiju, Folk Horror  
**Avoid when:** With no logical source below, a fire, a candle, a screen or water, it looks like a cheap trick. Used on every shot it turns from horror into a school play.  
**Prompt:** `uplight from below the chin, shadows climbing up the face onto the forehead, flickering firelight source on the ground`  
**Yields to:** `light.firelight` — No logical source below; a flame motivates the inversion.  
`light.under`

### Cross Lighting / Cross Key

**Also called:** cross key, double back key, opposing three-quarter keys  
**What it is:** Two sources at opposing angles behind and to the sides of the subject, each lighting one side, with a band of shadow left between them down the middle of the face. In a two-hander each source keys one actor and back lights the other.  
**Effect on the audience:** Strong sculpting with mystery kept at the centre. The face reads as drawn by two edges with a dark heart, and that feels like conflict.  
**Used for and where it works best:** The confrontation between two people at a table or in an alley, and the interrogation. Practically it is the smart answer to a night dialogue scene because two sources cover both actors and keep working whichever way the camera turns.  
**Best in:** formats: Feature Film, Drama Series Episode, Short Film, Trailer / Teaser, Anime (Japanese 2D), Game Cinematic / Gameplay, Music Video, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Crime / Procedural, Noir / Neo-Noir, Thriller / Suspense, Gangster, Drama, Western, Spy / Espionage, Seinen (mature anime)  
**Avoid when:** With both sources at identical intensity the face becomes symmetrical and dead, so keep one stronger. In a natural daylight scene it has no justification and reads as a studio.  
**Prompt:** `cross lighting, two opposing three quarter back keys, a band of shadow running down the centre of the face`  
**Yields to:** `light.bounce` — A natural daylight scene, where opposing keys read studio.  
`light.cross`

### Negative Fill

**Also called:** negative, subtractive lighting, black flag  
**What it is:** Instead of adding light you place a black surface beside the subject to absorb bounce and deepen the shadow. You sculpt by subtraction rather than addition.  
**Effect on the audience:** The face regains depth and direction without raising a single light level. The image feels purer because the shadow is a true shadow rather than a grey one.  
**Used for and where it works best:** Any space with white walls or wrapping ambient light: a hall, an office, a daylight street, a small studio. It is the cheapest and fastest way to turn a flat image into a cinematic one and it works even on a phone shoot for vertical content.  
**Best in:** formats: Documentary Feature, Interview / Video Podcast, Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Drama Series Episode, Corporate / Training, Wedding / Event Film, Feature Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Verite / Observational, True Crime, Thriller / Suspense, Romance, Historical / Biopic, Science / Educational  
**Avoid when:** Overdone, half the face goes black for no dramatic reason and you lose the performance. In a scene meant to feel bright and open, subtraction fights the mood.  
**Prompt:** `negative fill on camera right, black surface absorbing the bounce, deep clean shadow on that side of the face`  
`light.negative_fill`

### Bounce Light

**Also called:** reflected light, bounce board, ceiling bounce  
**What it is:** You aim the source at a pale surface, a white board, a ceiling, a wall or cloth, and the light reaches the subject after bouncing, which makes it wider, softer and weaker.  
**Effect on the audience:** Light that feels natural because it behaves the way real light behaves: the sun enters and bounces off the walls before it ever touches a face.  
**Used for and where it works best:** The realistic interior in drama and documentary, and whenever you want to light a whole room from one source. In heritage work bounce off sandy ground or a mud brick wall so the light picks up the colour of the place and becomes part of the world.  
**Best in:** formats: Feature Film, Drama Series Episode, Documentary Feature, Heritage / Historical Documentary, Interview / Video Podcast, Short Film, Wedding / Event Film, Corporate / Training, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Verite / Observational, Historical / Biopic, Heritage (civilisation-focused), Family, Romance, Slice of Life, Science / Educational  
**Avoid when:** Bouncing off a coloured surface puts a cast on the skin you will only notice in the edit. In a night scene a wide bounce erases the direction of the light and kills the night.  
**Prompt:** `light bounced off a white surface into the room, soft wrapping fill, natural falloff across the wall`  
**Yields to:** `light.practicals` — A night scene, where wide bounce erases direction.  
`light.bounce`

### Book Light

**Also called:** bounce through diffusion, double diffusion  
**What it is:** A source hits a bounce board and then passes through a diffusion frame, the two set up like an open book. That is a bounce followed by a diffusion in one unit.  
**Effect on the audience:** The softest light you can build while it still keeps a clear direction. The skin looks beautiful and the shadow is present but very gentle.  
**Used for and where it works best:** The close-up in drama, in premium commercials and in music performance, and the interview where the guest has to look their best. It is excellent for flashback and memory because it softens without losing the shape of the face.  
**Best in:** formats: Commercial / TVC, Feature Film, Music Video, Fashion Film, Interview / Video Podcast, Drama Series Episode, Wedding / Event Film, Product Video / Motion Design, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Romance, Drama, Melodrama, Musical, Family, Historical / Biopic, Rom-Com  
**Avoid when:** It needs space and has to sit close to the actor, so it fails in tight locations. In a harsh or realistic scene it reads as too kind and breaks the honesty of the image.  
**Prompt:** `book light setup, source bounced into white then pushed through diffusion, extremely soft directional light on the face`  
**Yields to:** `light.softbox` — A tight location with no room for it.  
`light.book_light`

### Gobo / Cookie Patterns

**Also called:** cucoloris, cookie, breakup pattern, shadow pattern  
**What it is:** You place a cut or perforated object between the source and the subject, a grid, a branch, a shutter or a window frame, and its shape prints as a shadow on the wall or the face.  
**Effect on the audience:** An empty wall becomes a place with a story. The shadow says there is a world outside the frame even though we never see it.  
**Used for and where it works best:** Any bare wall in an interior: the hotel room, the cell, the empty flat. In heritage work use a pattern shaped like a lattice screen or palm fronds and you fix the place and the period in one shot with no extra set dressing.  
**Best in:** formats: Feature Film, Drama Series Episode, Short Film, Heritage / Historical Documentary, Docudrama / Reenactment, Music Video, Commercial / TVC, Game Cinematic / Gameplay, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Noir / Neo-Noir, Crime / Procedural, Drama, Thriller / Suspense, Historical / Biopic, Heritage (civilisation-focused), Mystery / Whodunit, Gothic / Vampire  
**Avoid when:** If the shadow shape matches nothing that could exist in that room it reads as arbitrary decoration. A very sharp pattern across a face steals the performance.  
**Prompt:** `patterned shadow cast across the back wall from a lattice screen, hard source, the shape of the screen clearly readable`  
**Yields to:** `light.background_light` — The room can justify no pattern.  
`light.gobo`

### Venetian Blind Shadows / Jailhouse Bars

**Also called:** blind shadows, prison bar shadows, noir slats  
**What it is:** A hard source passing through horizontal slats or bars, throwing parallel stripes of light and shadow across the face and the wall. It is the oldest visual signature in noir.  
**Effect on the audience:** The character looks imprisoned even when they are free. The stripes cut the face, so you feel something binding them or someone watching them.  
**Used for and where it works best:** The detective in his office at night, the character about to betray someone, the person who knows they are wanted. In political and spy thrillers it delivers the feeling of surveillance without putting a single camera in the frame.  
**Best in:** formats: Feature Film, Drama Series Episode, Short Film, Trailer / Teaser, Music Video, Anime (Japanese 2D), Game Cinematic / Gameplay, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Noir / Neo-Noir, Crime / Procedural, Thriller / Suspense, Mystery / Whodunit, Spy / Espionage, Political Thriller, Gangster, Drama, Seinen (mature anime)  
**Avoid when:** It is one of the most worn images in cinema, so use it only when the scene is genuinely about confinement or surveillance. In a room that could never have slats it reads as a quotation rather than a choice.  
**Prompt:** `hard light through venetian blinds, horizontal bars of light and shadow striping the face and the back wall`  
**Example:** Double Indemnity (1944), the blind shadows falling across Walter Neff in his apartment.  
**Yields to:** `light.gobo` — A room that could never have slats.  
`light.venetian`

### Dappled Light / Leaf Shadow

**Also called:** leaf break-up, tree shadow, dapple  
**What it is:** Sun passing through leaves, dropping irregular moving patches of light and shadow across the face and the ground. Usually it drifts with a little wind.  
**Effect on the audience:** Life, nature, childhood and nostalgia. That small movement lets the shot breathe even when the camera and the subject are still.  
**Used for and where it works best:** The garden scene, childhood, first love, a walk and talk under trees, and the memory of a summer. In nature documentary it is simply the light of the forest, and in heritage work under palms it fixes the region in a single shot.  
**Best in:** formats: Feature Film, Drama Series Episode, Kids Content, Commercial / TVC, Music Video, Documentary Feature, Wedding / Event Film, Short Film, Anime (Japanese 2D), Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Romance, Family, Coming of Age, Slice of Life, Nature / Wildlife, Drama, Fairy Tale, Preschool / Early Learning  
**Avoid when:** Strong patches across a face in a close-up scramble the features and tire the eye. In a serious or tense scene it softens tension you did not want softened.  
**Prompt:** `dappled sunlight through leaves, soft moving patches of light and shadow drifting across the face and the ground`  
**Yields to:** `light.open_shade` — A close-up where patches scramble the features.  
`light.dappled`

### Practicals

**Also called:** practical lamps, in-frame sources  
**What it is:** Light sources visible inside the frame that are genuinely working: a table lamp, a chandelier, a shop sign, a candle, a screen. They are seen in the shot and they light the shot at the same time.  
**Effect on the audience:** The place becomes real and lived in. The viewer never asks where the light comes from because they can see it, and so they believe everything else in the frame.  
**Used for and where it works best:** Any night interior: the house, the cafe, the hotel, the street. It is the fastest way to make a shot feel cinematic, and because the sources are visible it works very well in vertical short-form where depth is limited and you need points of light to build layers.  
**Best in:** formats: Feature Film, Drama Series Episode, Vertical Short-Form (Reels, Shorts, TikTok), Vertical Micro-Drama, Music Video, Commercial / TVC, Documentary Feature, Short Film, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Drama, Romance, Crime / Procedural, Noir / Neo-Noir, Thriller / Suspense, Slice of Life, Coming of Age, Cyberpunk  
**Avoid when:** A lamp in the frame that lights nothing reads as empty dressing. Practicals pushed too far above exposure become dead white blobs in the image.  
**Colour temperature:** whichever the practical actually is — candle, household bulb, screen, lantern. Every one of them is a row in `light.kelvin_reference`, and a scene with three practicals has three figures  
**Prompt:** `lit by practicals only, a warm table lamp and a neon sign in frame, pools of light and darkness between them`  
`light.practicals`

### Motivated Lighting

**Also called:** source motivation, justified light  
**What it is:** Every fixture you place must have a justification inside the scene: a window, a lamp, a fire, a screen, an open door. The units stay hidden but their direction and colour match the visible source.  
**Effect on the audience:** The viewer never notices the lighting at all and therefore believes the world. This is the foundation of visual realism in modern cinema.  
**Used for and where it works best:** Realistic drama, documentary, reenactment and series work. In heritage and period work it is a governing rule: if the scene predates electricity every source must be sun, window, fire or oil lamp, otherwise one shot destroys the entire period.  
**Best in:** formats: Feature Film, Drama Series Episode, Documentary Feature, Heritage / Historical Documentary, Docudrama / Reenactment, Limited Series, Short Film, Soap Opera / Telenovela, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Historical / Biopic, Heritage (civilisation-focused), Verite / Observational, Crime / Procedural, Romance, War, Tragedy, Faith / Biblical Epic  
**Avoid when:** In commercials, music video and fantasy, insisting on motivation can block a better image for no gain. Half committing usually gives you the worst of both, because some sources motivated and some not reads as an accident rather than a system; the exception is a scene that deliberately crosses from the real world into a dream.  
**Prompt:** `fully motivated lighting, every source justified by a visible window and an oil lamp in the room, no unexplained light`  
**Yields to:** `light.dual_colour` — Commercial, music video or fantasy: image beats justification.  
`light.motivated`

### Available Light / Natural Light

**Also called:** natural light, existing light, no-light shooting  
**What it is:** Shooting with whatever light is already in the location without adding a single unit, where the most you do is use a reflector or move the subject relative to the window.  
**Effect on the audience:** Instant honesty. The image feels taken rather than made, and the viewer senses that this actually happened.  
**Used for and where it works best:** Documentary, field interviews, reportage and vlogging, and everyday scenes in realist drama. Inside a genuine archaeological site it is the cleanest choice because it preserves the real relationship between the architecture and the sun it was built for.  
**Best in:** formats: Documentary Feature, Documentary Series, News Report / Reportage, Vlog / YouTube Long-Form, Interview / Video Podcast, Vertical Short-Form (Reels, Shorts, TikTok), Feature Film, Heritage / Historical Documentary, Travel / Real Estate / Hospitality, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Verite / Observational, True Crime, Drama, Slice of Life, Nature / Wildlife, Historical / Biopic, Heritage (civilisation-focused), Coming of Age  
**Avoid when:** When the available light is genuinely bad, overhead fluorescents or a dark room, honesty does not make up for an image nobody can read. And when you need continuity across hours, natural light changes and breaks the scene.  
**Colour temperature:** the available-light row, then the daylight row that matches the sky that day — `light.kelvin_reference`  
**Prompt:** `available light only, lit by the room itself, no added fixtures, natural falloff toward the corners`  
**Yields to:** `light.motivated` — The existing light is too bad to read.  
`light.available`

### Soft Window Light

**Also called:** north light, indirect window light, open shade window  
**What it is:** Indirect daylight entering through a window, either open sky with no direct sun or sunlight that has already bounced, arriving wide and soft with a clear direction from the window side.  
**Effect on the audience:** Calm, intimacy and truth. The face is gently modelled and the room feels warm and inhabited.  
**Used for and where it works best:** Morning at home, a quiet conversation at a table, the character thinking by the window, and the documentary interview. Inside a mud brick house or a workshop it is the truest light available, because it is exactly the light the people of that place lived in.  
**Best in:** formats: Feature Film, Drama Series Episode, Documentary Feature, Interview / Video Podcast, Heritage / Historical Documentary, Short Film, Wedding / Event Film, Soap Opera / Telenovela, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Romance, Family, Slice of Life, Historical / Biopic, Heritage (civilisation-focused), Verite / Observational, Melodrama  
**Avoid when:** A window changes through the day, so a long scene loses continuity unless you control it. And if the subject stands too far from the window the falloff is brutal and they go dark fast.  
**Colour temperature:** open shade or overcast, not direct sun; that is the whole difference between this card and the hard window — `light.kelvin_reference`  
**Prompt:** `soft indirect window light from camera left, gentle directional falloff across the room, no direct sun`  
**Yields to:** `light.book_light` — A long scene a real window cannot hold.  
`light.window_soft`

### Hard Window Light / Direct Sun Through a Window

**Also called:** sun shaft through window, hot window  
**What it is:** Direct sun entering a window, drawing a hard rectangle of light on the floor or the wall and cutting the room into two halves, one burnt and one dark.  
**Effect on the audience:** Heat, harshness and the passing of the day. The rectangle itself becomes a character in the frame, and the viewer feels the hour and the season.  
**Used for and where it works best:** Midday at home, the waiting room, the cell, the sleeping figure the sun finally reaches. In period and heritage work the moving shaft on the floor is the simplest way to tell the passing of time in one locked shot.  
**Best in:** formats: Feature Film, Drama Series Episode, Heritage / Historical Documentary, Short Film, Docudrama / Reenactment, Music Video, Anime (Japanese 2D), AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, Historical / Biopic, Heritage (civilisation-focused), Western, Survival, Tragedy, War, Psychological / Arthouse  
**Avoid when:** If the rectangle lands on half a face by accident, the shot will not cut with its reverse. In a scene that needs softness it is the harshest possible choice.  
**Colour temperature:** direct sun — `light.kelvin_reference`  
**Prompt:** `hard direct sunlight through a window, a sharp bright rectangle on the floor, the rest of the room falling into shadow`  
**Yields to:** `light.window_soft` — The scene needs softness, or must cut with reverses.  
`light.window_hard`

### Vermeer Window Light

**Also called:** painterly window light, single window interior  
**What it is:** One soft window source entering from the left at chest height or a little above, with the rest of the room dark and completely unfilled, and the subject standing or seated at three quarters to it. Named after the Dutch painter Vermeer.  
**Effect on the audience:** Stillness and domestic dignity. An ordinary moment, a woman pouring water, a man writing, becomes sacred without any exaggeration.  
**Used for and where it works best:** Everyday labour in period drama, and heritage documentary when you film a craftsman, a scribe or a mother at home. It differs from ordinary window light in being staged as a painting: window on the left, dark depth, subject at a fixed angle.  
**Best in:** formats: Heritage / Historical Documentary, Feature Film, Docudrama / Reenactment, Short Film, Documentary Feature, Drama Series Episode, AI-Generated Clip, Experimental / Art Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Historical / Biopic, Heritage (civilisation-focused), Drama, Faith / Biblical Epic, Slice of Life, Tragedy, Melodrama, Verite / Observational  
**Avoid when:** It needs a room you can darken, because in an open space the bounce destroys the painting. And if you move the camera much you break the very composition the idea rests on.  
**Colour temperature:** open shade / north-facing window, which is the coolest row in the table and the reason this light looks the way it does — `light.kelvin_reference`  
**Prompt:** `single soft window light from the left at chest height, dark unfilled interior, subject at three quarters, painterly still composition`  
**Yields to:** `light.window_soft` — The camera moves, or the room cannot darken.  
`light.vermeer`

### Single-Source Lighting

**Also called:** one light setup, single source realism  
**What it is:** The entire scene is built on one source, and anything else reaching the subject arrives as natural bounce off walls and floor. There is no separate fill and no back light.  
**Effect on the audience:** Absolute credibility. The brain knows there is one sun and one fire, so any scene built on one source instantly feels true.  
**Used for and where it works best:** Night at home around a lamp, a cave, a tent, an interrogation room and any period scene before electricity. In heritage documentary it is the single most important lighting decision, because it recreates what the eye actually experienced in an age with only a window or a flame.  
**Best in:** formats: Feature Film, Heritage / Historical Documentary, Docudrama / Reenactment, Short Film, Drama Series Episode, Documentary Feature, Anime (Japanese 2D), AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Historical / Biopic, Heritage (civilisation-focused), Drama, Horror, Survival, War, Faith / Biblical Epic, Thriller / Suspense, Mythology / Ancient Epic  
**Avoid when:** In a wide shot of a large space a single source never reaches the edges and information is lost. In a two-hander one actor will always be dark unless you stage the movement around the source.  
**Prompt:** `single source lighting, one oil lamp on the table as the only light, everything else falling away into natural darkness`  
**Yields to:** `light.cross` — A two-hander, or a wide space one source misses.  
`light.single_source`

### God Rays / Volumetric Shafts

**Also called:** volumetric light, sunbeams, crepuscular rays, light shafts  
**What it is:** A beam of light made visible in itself because it passes through a medium carrying particles: dust, mist, smoke or steam. Light stops being the thing that reveals objects and becomes an object we can see.  
**Effect on the audience:** Sanctity, scale and distance. The space grows larger and the light feels as though it descends from a source above human reach.  
**Used for and where it works best:** Inside a temple, a church, a great hall, a forest at dawn or an abandoned warehouse. In heritage documentary it is the strongest single image of an ancient place of worship, and in epic work it declares the space matters before anyone speaks.  
**Best in:** formats: Heritage / Historical Documentary, Feature Film, Trailer / Teaser, Documentary Feature, Anime (Japanese 2D), 3D CG Animation, Game Cinematic / Gameplay, Music Video, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Heritage (civilisation-focused), Faith / Biblical Epic, Mythology / Ancient Epic, Fantasy / Epic, Historical / Biopic, Horror, Sci-Fi, Adventure, Drama  
**Avoid when:** Without a particle medium the shafts cannot exist, so asking for them in a clean space gives a fake image. Repeated in every shot they lose their sanctity and become wallpaper.  
**Prompt:** `strong volumetric light shafts falling through high windows into a dusty hall, visible beams cutting the darkness`  
`light.godrays`

### Haze / Atmosphere

**Also called:** atmos, light haze, atmosphere in the air  
**What it is:** A very light layer of suspended particulate spread through the whole space, never visible as a cloud, but giving every beam a body and every distance a measurable depth.  
**Effect on the audience:** The image gains layers and air. Distant objects sit paler than near ones, so the brain reads genuine depth.  
**Used for and where it works best:** Any large interior or night exterior you want to feel cinematic: the hall, the factory, the alley, the night street. It is the difference between a shot that looks like video and one that looks like film, and in heritage work it gives a temple the feeling of old standing air.  
**Best in:** formats: Feature Film, Drama Series Episode, Trailer / Teaser, Music Video, Commercial / TVC, Heritage / Historical Documentary, Game Cinematic / Gameplay, 3D CG Animation, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Thriller / Suspense, Noir / Neo-Noir, Horror, Sci-Fi, Fantasy / Epic, Heritage (civilisation-focused), Action, Cyberpunk, Mythology / Ancient Epic  
**Avoid when:** In a realistic daylight scene or honest documentary, haze makes the image feel manufactured. Too much of it kills contrast and everything turns grey with no true black.  
**Prompt:** `light atmospheric haze filling the room, visible depth layers, distant elements slightly lifted and pale`  
`light.haze`

### Smoke in Frame

**Also called:** practical smoke, smoke effect, visible smoke  
**What it is:** Smoke visible as an element in the image itself: from a fire, an incense burner, a vehicle, an explosion. It differs from haze in that it moves, has shape and shows its own edges.  
**Effect on the audience:** Movement and life in the frame even when everything else is still, plus a sense of danger, ritual or war depending on where it comes from.  
**Used for and where it works best:** The battle and its aftermath, temple ritual, the kitchen and the oven, the alley in the rain. In heritage work incense or oven smoke makes a scene feel lived in, and in advertising smoke around a product gives texture and prestige.  
**Best in:** formats: Feature Film, Trailer / Teaser, Music Video, Commercial / TVC, Heritage / Historical Documentary, Game Cinematic / Gameplay, Anime (Japanese 2D), 3D CG Animation, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: War, Action, Horror, Fantasy / Epic, Heritage (civilisation-focused), Mythology / Ancient Epic, Faith / Biblical Epic, Thriller / Suspense, Historical / Biopic  
**Avoid when:** Heavy smoke erases faces and action, so in a dialogue scene the performance is lost. Repeating the same smoke pattern in every shot looks like a cheap effect.  
**Prompt:** `visible smoke drifting through the frame, curling around the figures, catching the side light`  
**Yields to:** `light.haze` — A dialogue scene, where smoke erases the performance.  
`light.smoke`

### Temple Shaft / Light Through Dust in a Sacred Space

**Also called:** sacred shaft, oculus light, roof opening beam  
**What it is:** One strong beam descending from a roof opening or a high window into a very dark hall, made fully visible by suspended dust, landing as a clear disc or rectangle on the floor. It differs from general god rays in being a single beam deliberately staged as the centre of the composition.  
**Effect on the audience:** The space becomes sacred and the human becomes small. The viewer feels something above is speaking without a voice.  
**Used for and where it works best:** Inside a ziggurat, a temple, an old church or a royal tomb, and the moment a figure steps into the pool of light or out of it. It is one of the strongest shots in heritage documentary because it explains architecture and religion in one image with no narration.  
**Best in:** formats: Heritage / Historical Documentary, Feature Film, Documentary Feature, Trailer / Teaser, 3D CG Animation, Game Cinematic / Gameplay, Anime (Japanese 2D), AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Heritage (civilisation-focused), Faith / Biblical Epic, Mythology / Ancient Epic, Historical / Biopic, Fantasy / Epic, Drama, Adventure, Mystery / Whodunit  
**Avoid when:** It fails in an evenly lit space; everything else has to be genuinely dark. Add a second or third beam and the idea collapses back into ordinary windows.  
**Prompt:** `one single shaft of light falling from a roof opening into a dark stone hall, heavy dust in the beam, a bright pool on the floor`  
**Yields to:** `light.godrays` — More than one beam, or a space not dark.  
`light.temple_shaft`

### Golden Hour

**Also called:** sweet light, low sun  
**What it is:** The stretch just after sunrise or just before sunset, when the sun sits very low so the light turns warm and golden, arrives almost horizontally, and the shadows run long.  
**Effect on the audience:** Warmth, nostalgia, beauty and peace. The feeling is of a day ending or beginning, which is to say an ending or a promise.  
**Used for and where it works best:** The closing scene, the family gathering, the love beat, the traveller returning, and herding or harvest in heritage work. In family and travel advertising it is the fastest way to sell the feeling of home and safety, and in music video one shot of it works as an icon.  
**Best in:** formats: Feature Film, Commercial / TVC, Music Video, Travel / Real Estate / Hospitality, Heritage / Historical Documentary, Wedding / Event Film, Vertical Short-Form (Reels, Shorts, TikTok), Short Film, Documentary Feature, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Romance, Family, Drama, Heritage (civilisation-focused), Historical / Biopic, Western, Adventure, Melodrama, Road Movie  
**Avoid when:** It lasts only minutes, so bad planning costs you the whole scene. And if every shot is golden the piece looks like a greeting card and loses any capacity for harshness.  
**Colour temperature:** golden hour — `light.kelvin_reference`  
**Prompt:** `golden hour, very low warm sun from the side, long shadows across the ground, glowing rim on the subject`  
`light.golden_hour`

### Blue Hour

**Also called:** twilight, dusk light, civil twilight  
**What it is:** The stretch after the sun drops below the horizon and before full darkness, or the same window before sunrise. The sky stays luminous in a deep blue and there is no direct source at all.  
**Effect on the audience:** Loneliness, cold and transition. Time itself feels suspended, neither day nor night, so the character reads as caught between two states.  
**Used for and where it works best:** The scene of loss, departure or waiting, and the city before it wakes. It is the best window for exteriors of cities and archaeological sites, because the sky still holds detail while the artificial lights have come on, giving a balance impossible at any other hour.  
**Best in:** formats: Feature Film, Documentary Feature, Heritage / Historical Documentary, Travel / Real Estate / Hospitality, Music Video, Commercial / TVC, Drama Series Episode, Short Film, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Drama, Tragedy, Noir / Neo-Noir, Thriller / Suspense, Romance, Heritage (civilisation-focused), Historical / Biopic, Psychological / Arthouse, Road Movie  
**Avoid when:** It is very short and shifts minute by minute, so long takes will not match each other. Wait too long and the blue is gone and you are left with dead night.  
**Colour temperature:** blue hour — `light.kelvin_reference`  
**Prompt:** `blue hour, deep luminous blue sky after sunset, no direct sun, warm practical lights just coming on`  
**Yields to:** `light.moonlight_blue` — The blue is gone, or takes will not match.  
`light.blue_hour`

### Magic Hour

**Also called:** the golden window, twilight window  
**What it is:** The narrow window joining the end of golden hour to the start of blue hour, with the sun sitting right on the horizon. In practice it is a production constraint: twenty minutes at most.  
**Effect on the audience:** The light visibly changes in front of the viewer, so the moment feels fleeting and impossible to repeat. That is a rare sensation no artificial rig can give you.  
**Used for and where it works best:** The single shot carrying the whole meaning of the film: the goodbye, the last confession, the character choosing to leave. Shoot it on two cameras and bank the coverage, because tomorrow will not match.  
**Best in:** formats: Feature Film, Short Film, Music Video, Commercial / TVC, Travel / Real Estate / Hospitality, Heritage / Historical Documentary, Drama Series Episode, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Romance, Drama, Tragedy, Western, Heritage (civilisation-focused), Road Movie, Adventure, Melodrama  
**Avoid when:** A long dialogue scene planned inside it usually does not finish, because the light is gone in twenty minutes; the exception is a scene you can spread across several evenings on the same setup. In any scene that needs stable light for continuity it is the worst possible choice.  
**Colour temperature:** golden hour running into blue hour. The point of this card is that it moves, so state the figure at the head and the tail of the sequence rather than once — `light.kelvin_reference`  
**Prompt:** `magic hour, sun exactly on the horizon, sky glowing orange into deep blue, the light changing across the shot`  
**Yields to:** `light.golden_hour` — A scene too long for twenty minutes.  
`light.magic_hour`

### Sunrise Reveal

**Also called:** dawn reveal, first light reveal  
**What it is:** A shot that starts in darkness or deep blue and lets the rising sun progressively reveal the location or the figure, either as one long take or as a controlled time lapse.  
**Effect on the audience:** Birth, hope and beginning. The gradual reveal makes the viewer wait for the image and want it before it fully arrives.  
**Used for and where it works best:** The opening of an episode or a film, the end of a long night after a battle or a grief, and the first appearance of a city or a site in documentary. In heritage work it is the best establishing shot for a ziggurat or a temple because it dramatises the relationship with the sun the building was aligned to.  
**Best in:** formats: Heritage / Historical Documentary, Feature Film, Documentary Feature, Documentary Series, Travel / Real Estate / Hospitality, Title Sequence / Opening Credits, Music Video, Drama Series Episode, AI-Generated Clip | genres: Heritage (civilisation-focused), Historical / Biopic, Drama, Adventure, War, Faith / Biblical Epic, Nature / Wildlife, Mythology / Ancient Epic, Survival  
**Avoid when:** Used to open every episode it becomes a lazy motif. In a sad scene that does not end in hope, a sunrise contradicts the story.  
**Colour temperature:** the sunrise row while the sun is on the horizon, then the golden-hour row as it climbs — `light.kelvin_reference`  
**Prompt:** `sunrise reveal, the frame starting in blue darkness and the first warm light spreading across the stone facade`  
**Yields to:** `light.blue_hour` — A sad scene a sunrise would contradict.  
`light.sunrise_reveal`

### The Overcast Look

**Also called:** cloudy day light, giant softbox sky  
**What it is:** An overcast sky works as a giant diffuser, so the light arrives from everywhere with no clear direction and no hard shadow, at a relatively cool colour temperature.  
**Effect on the audience:** Neutrality, weight and a quiet melancholy. There is no drama in the light itself, so the viewer attends to faces and events instead of atmosphere.  
**Used for and where it works best:** Social drama, documentary, war and northern European settings, and the funeral or the waiting scene. Practically it is the best light for long days because it does not change and gives perfect continuity across hours.  
**Best in:** formats: Feature Film, Documentary Feature, Documentary Series, Drama Series Episode, News Report / Reportage, Short Film, Limited Series, Travel / Real Estate / Hospitality, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Drama, War, Tragedy, Verite / Observational, Crime / Procedural, True Crime, Psychological / Arthouse, Historical / Biopic, Survival  
**Avoid when:** It flattens faces and leaves a dead white sky, so keep as little sky in frame as you can. In a joyful scene or a travel commercial it is the enemy of the mood.  
**Colour temperature:** overcast — `light.kelvin_reference`  
**Prompt:** `overcast daylight, soft directionless light from a white sky, no hard shadows, muted cool tone`  
**Yields to:** `light.golden_hour` — A joyful scene or a travel commercial.  
`light.overcast`

### Open Shade

**Also called:** shade light, north side light  
**What it is:** You place the subject in shade, under a tree, beside a building or inside a doorway, while the rest of the location stays in sun, so the light reaching them comes from open blue sky and ground bounce.  
**Effect on the audience:** A soft comfortable face inside a harsh world. The contrast between the calm subject and the burnt background creates depth immediately.  
**Used for and where it works best:** The field interview in full sun and the daylight close-up with no equipment at all. In documentary and travel it is the fastest way to shoot a face at midday, and in heritage work standing under an arch or a gateway gives a clean face with architecture behind.  
**Best in:** formats: Documentary Feature, News Report / Reportage, Travel / Real Estate / Hospitality, Interview / Video Podcast, Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Heritage / Historical Documentary, Wedding / Event Film, Drama Series Episode, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Verite / Observational, Drama, Heritage (civilisation-focused), Historical / Biopic, Science / Educational, Nature / Wildlife, Slice of Life, Coming of Age  
**Avoid when:** Shade picks up blue from the sky and the skin turns cold unless you correct the balance. And the sunlit background clips easily into a white area that pulls the eye.  
**Colour temperature:** open shade — `light.kelvin_reference`  
**Prompt:** `subject standing in open shade under an arch, soft sky light on the face, bright sunlit background behind`  
`light.open_shade`

### The Blown-Out White World

**Also called:** overexposed white, clipped highlights look, white void  
**What it is:** A deliberately extreme exposure so the background and sky clip to featureless white and the edges bleed, leaving the subject at the centre with reduced detail.  
**Effect on the audience:** Erasure and dissolution. The viewer feels the location has vanished: a dream, a memory, a fever, a death, or a place that is not real.  
**Used for and where it works best:** The flashback, the dying or waking moment, the afterlife, and the acute hospital scene. In music video and advertising it gives a clean placeless world, and in vertical short-form it works as a very strong visual break.  
**Best in:** formats: Music Video, Feature Film, Commercial / TVC, Vertical Short-Form (Reels, Shorts, TikTok), Short Film, Anime (Japanese 2D), Title Sequence / Opening Credits, Experimental / Art Film, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Psychological / Arthouse, Surreal / Absurdist, Drama, Faith / Biblical Epic, Romance, Fantasy / Epic, Tragedy, Melodrama, Medical Drama  
**Avoid when:** Clipped white never comes back in the grade, so if it happens by mistake it cannot be fixed. Used in more than one sequence it stops reading as a time signal and starts reading as a camera error.  
**Prompt:** `heavily overexposed white background, the subject softly dissolving at the edges, dreamlike blown highlights`  
`light.blown_out`

### Day for Night

**Also called:** nuit americaine, american night  
**What it is:** Shooting in daylight with reduced exposure, filtration and a cold grade so the shot reads as night. You usually avoid the sky or darken it, and let the sun act as a side or back moonlight.  
**Effect on the audience:** A readable night. The viewer sees everything in the frame while still believing it is night, which is precisely the opposite of a real night.  
**Used for and where it works best:** The wide night chase, desert, sea and mountain at night, and any night scene in a location you could never light. In westerns and adventure it is the classic solution, and on a small production it is the difference between having a night scene and not shooting one at all.  
**Best in:** formats: Feature Film, Drama Series Episode, Short Film, Trailer / Teaser, Travel / Real Estate / Hospitality, Commercial / TVC, Music Video, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Western, Adventure, Action, War, Survival, Horror, Road Movie, Historical / Biopic, Thriller / Suspense  
**Avoid when:** Any hard sun shadow or a white sky exposes the trick instantly. In an intimate close scene the night looks manufactured and belief collapses.  
**Colour temperature:** shot on the daylight row and graded toward the moonlight one. `light.kelvin_reference` also carries the correction that moonlight is not blue, which is what this technique is pretending otherwise  
**Prompt:** `day for night, underexposed cold blue grade, sun used as hard moonlight from behind, sky kept out of frame`  
**Example:** Mad Max Fury Road (2015), the desert night chase shot in daylight and graded deep blue.  
**Yields to:** `light.night_for_night` — An intimate close scene, where the trick collapses.  
`light.day_for_night`

### Night for Night

**Also called:** true night shooting, real night  
**What it is:** Shooting at genuine night on existing or justified added sources: street poles, neon, car lights, fire. The black in frame is real black, not graded black.  
**Effect on the audience:** Complete credibility and genuine danger. The viewer accepts that there are areas they cannot see, and that acceptance is itself the source of tension.  
**Used for and where it works best:** Urban crime, noir and horror, and the street, the alley and the late cafe. Shooting an archaeological site at night it is the honest choice, because it lets the real architectural lighting become part of the image.  
**Best in:** formats: Feature Film, Drama Series Episode, Documentary Feature, Music Video, Vertical Short-Form (Reels, Shorts, TikTok), Vertical Micro-Drama, Short Film, Heritage / Historical Documentary, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Crime / Procedural, Noir / Neo-Noir, Thriller / Suspense, Horror, Drama, Cyberpunk, Gangster, True Crime, Romance  
**Avoid when:** It costs time, crew and support lighting, and on a weak camera it turns into noise rather than night. And if you light it enough to see everything you lose the reason you shot at night in the first place.  
**Colour temperature:** whatever the practicals are — sodium, neon, headlight, window spill. There is no single figure for a night exterior and inventing one is how the sequence goes grey — `light.kelvin_reference`  
**Prompt:** `true night exterior, lit only by street lamps and shop signs, deep real blacks between the pools of light`  
**Yields to:** `light.day_for_night` — No crew, weak camera, or an unlightable wide.  
`light.night_for_night`

### Moonlight Blue

**Also called:** movie moonlight, blue night convention  
**What it is:** A cinematic convention: moonlight is rendered blue, relatively hard and coming from one high direction. Moonlight is not physically blue, but the eye sees colder in darkness and the convention settled from there.  
**Effect on the audience:** Instant readable night. The viewer does not need to see the moon; the blue alone says night.  
**Used for and where it works best:** Any night exterior or interior with a window: sleeping, escaping, standing watch, the ambush. In heritage and epic work blue moonlight on stone and sand delivers a mythic night with no artificial source visible in frame.  
**Best in:** formats: Feature Film, Drama Series Episode, Anime (Japanese 2D), 3D CG Animation, Trailer / Teaser, Game Cinematic / Gameplay, Heritage / Historical Documentary, Music Video, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Fantasy / Epic, Horror, Thriller / Suspense, Drama, Mythology / Ancient Epic, Heritage (civilisation-focused), War, Gothic / Vampire, Adventure  
**Avoid when:** Overdone blue makes skin look dead. And if there is a warm source in the scene, a fire or a lamp, you must keep a colour contrast between them or the whole frame goes blue and means nothing.  
**Colour temperature:** moonlight reads slightly warm, because it is reflected sunlight; the blue is a convention rather than a measurement. `light.kelvin_reference` carries both the figure and the range the convention is usually graded to  
**Prompt:** `cool blue moonlight from a high side angle, hard edged shadows, warm practical lamp inside for contrast`  
`light.moonlight_blue`

### Hospital Flat White

**Also called:** institutional white, clinical light  
**What it is:** A cold white light spread evenly from the ceiling with no direction and no visible shadow, on pale walls and floors that bounce it back.  
**Effect on the audience:** Sterility and a cold dread. The feeling of being inside a system that does not care about you, which is an institutional threat rather than a personal one.  
**Used for and where it works best:** The hospital, the lab, the examination room, the government office, the modern prison. In medical drama and psychological thriller it is the light of losing control, and in sci-fi and dystopia it is the light of the state.  
**Best in:** formats: Feature Film, Drama Series Episode, Limited Series, Short Film, Documentary Feature, Commercial / TVC, Anime (Japanese 2D), Game Cinematic / Gameplay, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Medical Drama, Psychological Horror, Dystopia / Post-Apocalyptic, Sci-Fi, Thriller / Suspense, Drama, Body Horror, True Crime  
**Avoid when:** With no dramatic reason it is simply ugly light that flattens faces. In an emotional scene it blocks the viewer from getting close to the character.  
**Prompt:** `flat cold white institutional lighting from overhead panels, no shadows, pale reflective walls and floor`  
**Yields to:** `light.high_key` — An emotional scene the clinical cold blocks.  
`light.hospital_white`

### Institutional Fluorescent Green

**Also called:** strip light green, office tube light  
**What it is:** Old fluorescent tubes with a deficient spectrum that skews green, mounted overhead in rows, so skin picks up the cast and faces look unwell.  
**Effect on the audience:** Decay, tedium and sickness. The place feels neglected and the people inside it trapped in a dead routine.  
**Used for and where it works best:** The parking garage, the apartment corridor, the late night shop, the office, the laundromat, the public toilet. In crime and thriller it is the light of places where bad things happen, and in dark comedy it turns an office into a prison.  
**Best in:** formats: Feature Film, Drama Series Episode, Short Film, Music Video, Game Cinematic / Gameplay, Vertical Short-Form (Reels, Shorts, TikTok), Anime (Japanese 2D), AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Crime / Procedural, Thriller / Suspense, Noir / Neo-Noir, Dark Comedy / Satire, Psychological Horror, Dystopia / Post-Apocalyptic, Drama, True Crime, Seinen (mature anime)  
**Avoid when:** A green cast on skin is hard to remove in the grade, so it has to be a deliberate decision from the first shot. In a warm or family scene it kills all sympathy.  
**Colour temperature:** fluorescent has a figure; the green does not. It is a gap in the spectrum, so it needs a magenta correction and cannot be reached by changing Kelvin — `light.kelvin_reference`  
**Prompt:** `overhead fluorescent tubes with a sickly green cast, flat institutional light, faces looking pale and unwell`  
**Yields to:** `light.hospital_white` — The green cannot be committed to from shot one.  
`light.fluorescent_green`

### Sodium Vapour Orange

**Also called:** street lamp orange, monochrome sodium  
**What it is:** Old sodium street lamps produce an almost single wavelength orange, so every colour under them collapses into orange and black.  
**Effect on the audience:** Nostalgia, city and a low grade danger. It feels like a real night in a real neighbourhood rather than a designed one.  
**Used for and where it works best:** The alley, the car park, the motorway at night, the character coming home late. It is excellent for crime and social realism, and very strong when you set it against a blue or white source in the same frame to build two layers.  
**Best in:** formats: Feature Film, Drama Series Episode, Music Video, Vertical Short-Form (Reels, Shorts, TikTok), Short Film, Vertical Micro-Drama, Game Cinematic / Gameplay, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Crime / Procedural, Drama, Noir / Neo-Noir, Thriller / Suspense, Coming of Age, Romance, True Crime, Slice of Life  
**Avoid when:** It destroys every other colour, so if something in the scene depends on its own colour it will be lost. Used across all your night scenes the whole city becomes one flat hue.  
**Colour temperature:** high-pressure sodium has a figure. Low-pressure sodium has none at all — it is near-monochromatic, and nothing lit by it has a true hue — `light.kelvin_reference`  
**Prompt:** `sodium vapour street lamps, monochrome orange night, colours collapsing into orange and black`  
**Yields to:** `light.night_for_night` — Something in the scene depends on its own colour.  
`light.sodium_vapour`

### Tungsten Warmth

**Also called:** incandescent warmth, warm domestic light  
**What it is:** Ordinary tungsten bulbs give a warm light at a low colour temperature, orange leaning yellow. It is the default light of any home before the age of LED.  
**Effect on the audience:** Home, safety and human warmth. The feeling of being inside somewhere that belongs to someone rather than somewhere public.  
**Used for and where it works best:** Evening at home, the grandmother's room, the old cafe and the dinner table. In flashback and period drama it is the key to time: the warmth alone says this is the past, and set against a blue window it gives you a two colour frame.  
**Best in:** formats: Feature Film, Drama Series Episode, Soap Opera / Telenovela, Documentary Feature, Heritage / Historical Documentary, Commercial / TVC, Wedding / Event Film, Short Film, Music Video, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Drama, Family, Romance, Melodrama, Historical / Biopic, Heritage (civilisation-focused), Coming of Age, Slice of Life  
**Avoid when:** If the whole scene is warm with nothing cool against it, colour depth vanishes and everything goes yellow. In a modern technological setting it puts the story in the wrong decade.  
**Colour temperature:** tungsten, which is the reference every tungsten stock is balanced to — `light.kelvin_reference`  
**Prompt:** `warm tungsten practical lamps, low colour temperature, orange pools of light in a dark room`  
`light.tungsten_warm`

### Neon Lighting

**Also called:** neon signs, tube sign light  
**What it is:** Coloured neon signs inside the frame working as real sources, throwing saturated colour straight onto faces and surfaces: pink, cyan, red, green.  
**Effect on the audience:** City, night, appetite and danger. The colour itself becomes a psychological state and the character reads as part of an artificial world.  
**Used for and where it works best:** The alley, the bar, the cheap hotel, the wet street, and music video and vertical content. In cyberpunk and neo-noir it is the primary light, and in advertising it delivers instant youth energy.  
**Best in:** formats: Music Video, Vertical Short-Form (Reels, Shorts, TikTok), Feature Film, Drama Series Episode, Commercial / TVC, Vertical Micro-Drama, Game Cinematic / Gameplay, Trailer / Teaser, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Cyberpunk, Noir / Neo-Noir, Crime / Procedural, Thriller / Suspense, Romance, Sci-Fi, Drama, Coming of Age, Dystopia / Post-Apocalyptic  
**Avoid when:** It is heavily overused on social platforms, so without a story reason it reads as imitation. And saturated colour on a face distorts skin tone in a way that is hard to recover.  
**Colour temperature:** none. Neon has a colour, not a temperature — `light.kelvin_reference`  
**Prompt:** `neon signs lighting the scene, magenta and cyan reflections on wet pavement, saturated colour on the faces`  
**Yields to:** `light.sodium_vapour` — No story reason: a real street, not a designed one.  
`light.neon`

### Blinking Neon / Faulty Sign

**Also called:** flickering sign, stuttering neon  
**What it is:** A neon sign or a broken lamp cutting on and off at an irregular rhythm, so the scene alternates between two lighting states inside a single shot.  
**Effect on the audience:** Anxiety and instability. The brain cannot settle into the rhythm so it stays alert, and the gaps suggest something might appear or vanish in the dark.  
**Used for and where it works best:** The cheap hotel, the corridor, the abandoned hospital, and anywhere the story has started to fall apart. In horror use it so something disappears in the dark beat and appears in the lit one, which is the cleanest way to build a shock without a cut.  
**Best in:** formats: Feature Film, Drama Series Episode, Music Video, Vertical Short-Form (Reels, Shorts, TikTok), Short Film, Game Cinematic / Gameplay, Anime (Japanese 2D), Trailer / Teaser, AI-Generated Clip | genres: Horror, Thriller / Suspense, Noir / Neo-Noir, Crime / Procedural, Psychological Horror, Cyberpunk, Supernatural Horror, Dystopia / Post-Apocalyptic  
**Avoid when:** In a dialogue scene it stops the audience reading faces. A faulty sign or a flickering bulb in a scene is ordinary light, not a flash question: write the rhythm the scene wants, and irregular reads real. Only a deliberate strobe or rapid flash sequence is `safety.photosensitive_flash`.  
**Colour temperature:** none, as with any neon; give the ambient a figure and the sign a colour — `light.kelvin_reference`  
**Prompt:** `a faulty neon sign cutting on and off, the corridor alternating between magenta light and darkness`  
*(the rhythm is the scene's: write it in the prompt as the scene wants it, since an ordinary faulty sign is not a flash question. Only a deliberate strobe or rapid flash sequence goes to `safety.photosensitive_flash`.)*  
**Yields to:** `light.neon` — A dialogue scene, where flicker blocks faces.  
`light.blinking_neon`

### Dual-Colour Lighting

**Also called:** two colour light, teal and magenta setup, colour contrast lighting  
**What it is:** Two sources in opposing colours on either side of the subject: cyan or blue on one side, magenta or orange on the other, with the face carrying both.  
**Effect on the audience:** Division, tension and a modern feel. The viewer reads a character caught between two worlds without anyone explaining it.  
**Used for and where it works best:** Music video, vertical short-form and trailers, and the scene where a character sits between two choices. In cyberpunk and sci-fi it is standard, and in drama use it for a single beat when a decision splits the character in two.  
**Best in:** formats: Music Video, Vertical Short-Form (Reels, Shorts, TikTok), Trailer / Teaser, Commercial / TVC, Game Cinematic / Gameplay, Vertical Micro-Drama, Drama Series Episode, Anime (Japanese 2D), AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Cyberpunk, Sci-Fi, Thriller / Suspense, Drama, Musical, Action, Dystopia / Post-Apocalyptic, Psychological / Arthouse  
**Avoid when:** It has become one of the most repeated looks in modern video, so use it when the two colours actually mean something in the story. In documentary and realist drama it looks entirely manufactured.  
**Prompt:** `dual colour lighting, cyan rim from camera left and magenta key from camera right, the two colours meeting across the face`  
**Yields to:** `light.motivated` — Documentary or realist drama, where it reads manufactured.  
`light.dual_colour`

### The One-Lamp Interrogation

**Also called:** interrogation light, single hanging bulb  
**What it is:** One hanging or directed lamp above a table, lighting a small disc and leaving everything around it black, with the subject seated directly beneath it.  
**Effect on the audience:** Siege and pressure. The character has nowhere to go, and the light itself has become an instrument of interrogation rather than of seeing.  
**Used for and where it works best:** The interrogation, the confession or the reckoning, and any moment a character is caught. In procedural, crime and thriller it is the iconic image, and you can invert it: keep the interrogator in the dark and the suspect in the light, or flip it when the power in the scene changes hands.  
**Best in:** formats: Feature Film, Drama Series Episode, Short Film, Trailer / Teaser, Game Cinematic / Gameplay, Anime (Japanese 2D), Music Video, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Crime / Procedural, Noir / Neo-Noir, Thriller / Suspense, Mystery / Whodunit, War, Political Thriller, Spy / Espionage, True Crime, Seinen (mature anime)  
**Avoid when:** It is a heavily worn image, so without an inversion or a new angle it reads as a quotation. And in a scene meant to show a modern lawful procedure, the hanging bulb looks borrowed from an old film.  
**Prompt:** `one hanging lamp over a metal table, a small pool of light on the seated figure, everything beyond it in total blackness`  
**Yields to:** `light.tv_glow` — The scene is about the institution, not the interrogator.  
`light.interrogation`

### Firelight Flicker

**Also called:** fire flicker, campfire light, hearth light  
**What it is:** Warm orange light from an open flame, shifting in intensity and direction irregularly several times a second, and usually arriving from a low level.  
**Effect on the audience:** Life, intimacy and danger at once. The flicker makes a face move even when it is still, so the moment feels alive rather than recorded.  
**Used for and where it works best:** The story circle around a fire, the camp, night in a cave or a tent, war after the fighting. In heritage work it is the only honest light for a night scene before electricity, and framing faces in a ring around it tells you about a community without a word.  
**Best in:** formats: Feature Film, Heritage / Historical Documentary, Docudrama / Reenactment, Drama Series Episode, Short Film, Anime (Japanese 2D), 3D CG Animation, Game Cinematic / Gameplay, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Heritage (civilisation-focused), Historical / Biopic, Survival, Mythology / Ancient Epic, War, Horror, Folk Horror, Adventure, Drama  
**Avoid when:** A mechanical evenly timed flicker reads as fake immediately; it has to be irregular. And if the fire is out of frame with nothing to indicate it, the viewer feels light with no cause. Firelight, however it flickers, is ordinary light and never a photosensitivity question.  
**Colour temperature:** open fire, which flickers in temperature as well as in level — `light.kelvin_reference`  
**Prompt:** `warm firelight from below, irregular flicker across the faces, orange light falling off fast into darkness`  
`light.firelight`

### Candlelight

**Also called:** single flame light, taper light  
**What it is:** A very small flame as the only source, weak and close, so the light falls off extremely fast the moment the subject moves a few centimetres away.  
**Effect on the audience:** Extreme intimacy and fragility. The world has shrunk to a small circle and everything outside it is unknown.  
**Used for and where it works best:** Prayer, confession, the letter read at night, the sickroom and the ritual. In period and heritage work it is the truest night interior, and in horror a candle makes the audience watch the dark edges instead of the face.  
**Best in:** formats: Feature Film, Heritage / Historical Documentary, Docudrama / Reenactment, Short Film, Drama Series Episode, Anime (Japanese 2D), Music Video, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Historical / Biopic, Heritage (civilisation-focused), Faith / Biblical Epic, Gothic / Vampire, Horror, Drama, Romance, Tragedy, Mythology / Ancient Epic  
**Avoid when:** One candle will not expose a wide shot, so either group several or support it with a hidden unit matched in colour and direction. And if the candle is in frame while the face is lit from another side, the lie is exposed instantly.  
**Colour temperature:** candle — `light.kelvin_reference`  
**Prompt:** `single candle as the only light source, extremely fast falloff, warm flame flicker on the face, darkness beyond`  
`light.candlelight`

### The Lantern Walk

**Also called:** moving practical carried by the actor, handheld lamp walk  
**What it is:** The character carries the source in their hand, a lantern, an oil lamp, a candle or a torch, and walks through a dark space, so the light travels with them and the location is revealed progressively as they move.  
**Effect on the audience:** The viewer discovers the space at the same instant as the character and becomes their partner in fear or wonder. Movement inside the shot builds tension with no cut at all.  
**Used for and where it works best:** Entering a temple, a tomb, a cellar or an abandoned house, and searching at night. In heritage documentary it is the strongest exploration shot for an interior site, and in horror it is the rule: you see only what the person holding the lantern sees.  
**Best in:** formats: Feature Film, Heritage / Historical Documentary, Documentary Feature, Short Film, Game Cinematic / Gameplay, Anime (Japanese 2D), Trailer / Teaser, Drama Series Episode, AI-Generated Clip | genres: Horror, Mystery / Whodunit, Heritage (civilisation-focused), Adventure, Historical / Biopic, Gothic / Vampire, Folk Horror, Supernatural Horror, Fantasy / Epic  
**Avoid when:** If the space is already lit from other sources the lantern becomes a prop with no function. And if the actor swings their arm the light slams into their own face and the shot turns ugly.  
**Colour temperature:** oil lantern; if the walk also carries a candle or a torch those are separate rows — `light.kelvin_reference`  
**Prompt:** `a figure carrying an oil lamp through a dark stone corridor, the light travelling with them and revealing carvings as they pass`  
`light.lantern_walk`

### Lighting a Match

**Also called:** match strike, flame ignition beat  
**What it is:** A small ignition inside total darkness: the match catches, flares hard for the first second, then settles into a low flame lighting only a face or a pair of hands.  
**Effect on the audience:** The birth of light. The sudden flare exposes a face we could not see, so the shot becomes an announcement of presence or the start of a plan.  
**Used for and where it works best:** Introducing a character in darkness, opening a scene in an unknown place, and any decision beat that follows silence. It is excellent as a transition point in a trailer because it gives a natural jump in exposure you can cut on.  
**Best in:** formats: Feature Film, Trailer / Teaser, Short Film, Music Video, Anime (Japanese 2D), Game Cinematic / Gameplay, Vertical Short-Form (Reels, Shorts, TikTok), Drama Series Episode, AI-Generated Clip | genres: Noir / Neo-Noir, Crime / Procedural, Thriller / Suspense, Western, Horror, Gangster, War, Mystery / Whodunit, Spy / Espionage  
**Avoid when:** It needs genuine darkness before it, because in a lit room the moment disappears entirely. Repeated in the same piece it stops being an event and becomes a smoking habit.  
**Colour temperature:** match, the warmest source in the table — `light.kelvin_reference`  
**Prompt:** `a match struck in total darkness, a bright flare for a second then settling to a small flame lighting the face and hands`  
`light.match_strike`

### Flashlight Beam / Torch Beam

**Also called:** torchlight, searchlight beam, handheld beam  
**What it is:** A narrow directed beam from a torch in the character's hand, lighting a small circle and leaving everything outside it black. The beam itself is often visible if there is dust or mist.  
**Effect on the audience:** The fear lives in the area the beam does not reach. It literally defines our attention, so the director steers our eyes the same way they steer the actor's hand.  
**Used for and where it works best:** Searching an abandoned house, a forest or a tunnel, the police scene, and diving. In horror and found footage it is the base language, and in documentary inside a dark site it delivers a genuine feeling of discovery.  
**Best in:** formats: Feature Film, Short Film, Game Cinematic / Gameplay, Vertical Short-Form (Reels, Shorts, TikTok), Documentary Feature, Heritage / Historical Documentary, Anime (Japanese 2D), Trailer / Teaser, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Horror, Thriller / Suspense, Found Footage, Mystery / Whodunit, Crime / Procedural, Survival, Supernatural Horror, Adventure, True Crime  
**Avoid when:** Swung fast and without a pattern the beam makes the scene unreadable and tiring. And in any space with ambient light the beam does not register and its whole value is lost.  
**Prompt:** `a handheld torch beam cutting through the dark, a small visible circle of light, the beam itself catching the dust`  
`light.torch_beam`

### Car Headlight Sweep

**Also called:** passing headlights, car light wipe  
**What it is:** A strong light travelling across the space from one side to the other from a passing vehicle, washing faces and walls with moving light before it leaves and the darkness returns.  
**Effect on the audience:** The world outside exists and keeps going without caring about the character. In a tense scene, each pass reveals something new or makes the viewer dread what the next one will show.  
**Used for and where it works best:** The night room beside a street, waiting inside a parked car, and hiding. It is the fastest way to make a static night scene feel alive, and in vertical micro-drama it puts movement in the frame without moving the camera.  
**Best in:** formats: Feature Film, Drama Series Episode, Vertical Micro-Drama, Vertical Short-Form (Reels, Shorts, TikTok), Short Film, Music Video, Game Cinematic / Gameplay, AI-Generated Clip | genres: Crime / Procedural, Noir / Neo-Noir, Thriller / Suspense, Drama, Romance, Horror, Gangster, Coming of Age, True Crime  
**Avoid when:** If the room is on the tenth floor a passing car cannot reach it, so the logic has to hold. And repeated too quickly it starts to look like a nightclub.  
**Colour temperature:** halogen headlight. An LED headlight is a different row and far colder, which is the whole difference between a period street and a modern one — `light.kelvin_reference`  
**Prompt:** `headlights from a passing car sweeping across the dark room, light travelling over the wall and the face then leaving`  
`light.headlight_sweep`

### Police Light Sweep

**Also called:** emergency light, siren light, red and blue rotation  
**What it is:** Blue and red light rotating at a steady rhythm from an emergency vehicle, washing the location in two alternating colours with a fixed rotational pattern.  
**Effect on the audience:** A disaster has already happened. The two colours alone announce that something bad is over, so the viewer knows the outcome before seeing the event.  
**Used for and where it works best:** The end of a crime scene, the ambulance arriving, the character watching from a distance. It is excellent in trailers and true crime as a half second signal, and you never have to see the vehicle at all.  
**Best in:** formats: Feature Film, Drama Series Episode, Trailer / Teaser, Documentary Feature, News Report / Reportage, Vertical Short-Form (Reels, Shorts, TikTok), Music Video, Game Cinematic / Gameplay, AI-Generated Clip | genres: Crime / Procedural, True Crime, Thriller / Suspense, Drama, Noir / Neo-Noir, Disaster, Political Thriller, Action, Medical Drama  
**Avoid when:** A perfectly regular rotation looks digital and fake, so let the rhythm drift slightly. And in a scene meant to be quiet, the two colours shout and destroy the grief. The drift is a realism note. An emergency light turning in a scene is ordinary light, not a flash question; it becomes `safety.photosensitive_flash` only if the piece turns it into a deliberate strobe or rapid flash sequence.  
**Colour temperature:** none. Saturated red and blue is not a white point; balance the ambient and write the sweep as colour — `light.kelvin_reference`  
**Prompt:** `red and blue emergency lights rotating across the street, alternating colour washing the faces and the wet asphalt`  
`light.police_sweep`

### Lightning Flash

**Also called:** lightning strike, storm flash  
**What it is:** A very strong short flash lighting the whole space from one direction, usually a window, before darkness returns at once. It normally arrives as two or three quick pulses rather than one.  
**Effect on the audience:** A violent instantaneous reveal. The viewer sees something for a fraction of a second and keeps doubting what they saw, and that doubt is stronger than any clear image.  
**Used for and where it works best:** Horror and gothic: a figure standing in the corridor seen in one pulse and gone by the next, or a face whose expression changes. In drama pair the flash with the peak of a confession so the storm outside matches the one inside.  
**Best in:** formats: Feature Film, Drama Series Episode, Anime (Japanese 2D), Trailer / Teaser, Game Cinematic / Gameplay, Short Film, Music Video, 3D CG Animation, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Horror, Gothic / Vampire, Supernatural Horror, Thriller / Suspense, Melodrama, Folk Horror, Fantasy / Epic, Tragedy, Monster / Kaiju  
**Avoid when:** Lightning with no rain, no thunder and no cloud reads as a cheap effect. Repeated on every shot in a scene it turns from an event into disco lighting. A storm flash or two in a scene is weather and ordinary light, not a flash question; only a deliberate rapid run of flashes is `safety.photosensitive_flash`.  
**Colour temperature:** lightning, the coolest row there is — `light.kelvin_reference`  
**Prompt:** `lightning flash through the window lighting the whole room, then instant darkness, hard shadows thrown across the wall`  
*(the pulse count is deliberately not specified here. This field used to say "two quick pulses" — a number the Avoid when above had already handed to `safety.photosensitive_flash`, still shipping to the generator.)*  
`light.lightning`

### Strobe Light

**Also called:** strobing, stroboscopic light  
**What it is:** Fast even repeated pulses, so movement breaks into a series of frozen positions instead of a continuous flow. The source is usually a dance floor, an alarm or an electrical fault.  
**Effect on the audience:** Loss of control and disorientation. The brain cannot assemble the motion so it feels dizzy and anxious, while on a dance floor the same thing reads as high energy.  
**Used for and where it works best:** The club, the party, a fight inside a crowd, and a panic attack or a fractured memory. In music video and short-form it gives instant energy, and in psychological thriller it makes the audience feel the character's state instead of observing it.  
**Best in:** formats: Music Video, Vertical Short-Form (Reels, Shorts, TikTok), Feature Film, Concert / Live Event, Game Cinematic / Gameplay, Trailer / Teaser, Anime (Japanese 2D), Dance Film, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Musical, Thriller / Suspense, Psychological Horror, Action, Horror, Cyberpunk, Sci-Fi, Surreal / Absurdist  
**Avoid when:** In a dialogue scene it erases the entire performance. And a strobe is the clearest case of a shot that can injure a photosensitive viewer — this card deliberately no longer says *keep the frequency low and carry a warning*, because that was a dosage nobody here is qualified to set; the rule and the stopping point are `safety.photosensitive_flash`.  
**Colour temperature:** xenon strobe — `light.kelvin_reference`  
**Prompt:** `strobe light pulses on the dance floor, movement breaking into frozen positions, short bursts of white light`  
**Yields to:** `safety.photosensitive_flash` — Flash rate and stopping point - a safety authority, not a look.  
`light.strobe`

### TV Glow / Screen Glow

**Also called:** television light, monitor glow  
**What it is:** Shifting light in colour and intensity from a television or a monitor in the room, usually leaning blue and fluctuating with whatever is playing on the screen.  
**Effect on the audience:** A modern loneliness. The character is lit by something that is not real, so they look alone even while the screen talks and laughs.  
**Used for and where it works best:** The character awake alone, the child sitting too close to the set, the room where the television has not been off for days. In drama and thriller it is the light of domestic siege, and in horror it gives a source that changes without reason and hides things in the corners.  
**Best in:** formats: Feature Film, Drama Series Episode, Vertical Micro-Drama, Short Film, Vertical Short-Form (Reels, Shorts, TikTok), Music Video, Anime (Japanese 2D), Game Cinematic / Gameplay, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Drama, Horror, Thriller / Suspense, Psychological / Arthouse, Coming of Age, Slice of Life, Psychological Horror, True Crime  
**Avoid when:** Make the fluctuation too fast and it looks manufactured and tires the eye. In a scene meant to feel warm and familial, that cold blue flips the feeling against your intention.  
**Colour temperature:** the screen row, which is a standard white point; a set showing a warm image shifts it — `light.kelvin_reference`  
**Prompt:** `flickering blue television glow lighting the room, light level shifting with the screen content, the rest in darkness`  
**Yields to:** `light.tungsten_warm` — A scene meant to feel warm and familial.  
`light.tv_glow`

### Phone Glow on a Face

**Also called:** screen light on face, device uplight  
**What it is:** Weak white or blue light from a phone screen held below the face, lighting the chin, the nose and the underside of the eyes while the forehead and the background stay dark.  
**Effect on the audience:** Contemporary isolation and a private tension. A face lit from below by a screen says the character is reading a message or a piece of news that changes something.  
**Used for and where it works best:** The moment the news arrives, the exposure, a chase conducted through messages, the teenager at night. In vertical micro-drama and short-form it is the most readable close-up on a phone screen, and because every viewer knows this light from their own life they believe it instantly.  
**Best in:** formats: Vertical Micro-Drama, Vertical Short-Form (Reels, Shorts, TikTok), Feature Film, Drama Series Episode, Short Film, Music Video, Anime (Japanese 2D), AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Thriller / Suspense, Drama, Coming of Age, Horror, Romance, Psychological / Arthouse, Crime / Procedural, True Crime, Slice of Life  
**Avoid when:** Pushed too bright it becomes horror uplight and the character turns sinister by accident. And if the screen is in frame but its light does not match the face, the trick is exposed.  
**Colour temperature:** the screen row, except in night mode, which shifts it far warmer and is the commonest real-world case — `light.kelvin_reference`  
**Prompt:** `pale phone screen glow lighting the face from below, forehead and background in darkness, faint blue cast on the skin`  
`light.phone_glow`

### Underwater Caustics / Water Reflections

**Also called:** caustics, pool light patterns, water ripple light  
**What it is:** Light passing through a moving water surface refracts and draws a shifting net of bright lines across bodies and walls, both underwater and above it.  
**Effect on the audience:** Dream, fluidity and weightlessness. That organic movement makes the scene feel outside ordinary time or inside a memory.  
**Used for and where it works best:** The pool, the river and the bath, and any beat of drowning, birth or purification. In heritage work on a wall near a river or a basin it makes the place feel alive, and in commercials and music video it adds a luxurious texture with nothing else added.  
**Best in:** formats: Feature Film, Music Video, Commercial / TVC, Documentary Feature, Short Film, Anime (Japanese 2D), 3D CG Animation, Game Cinematic / Gameplay, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Drama, Romance, Fantasy / Epic, Psychological / Arthouse, Surreal / Absurdist, Nature / Wildlife, Horror, Mythology / Ancient Epic, Coming of Age  
**Avoid when:** Put the caustics on a wall with no plausible water nearby and it reads as a filter. And a very fast pattern scrambles a face in close-up.  
**Prompt:** `water caustics rippling across the wall and the skin, shifting net of bright lines, soft blue reflected light`  
**Yields to:** `light.dappled` — No plausible water; leaves breathe the same way.  
`light.caustics`

### Stage Spotlight / Follow Spot

**Also called:** followspot, theatre spot, pin spot  
**What it is:** A narrow defined beam from above isolating the subject inside a circle of light with everything around it black. The follow version tracks the performer and keeps them inside the circle.  
**Effect on the audience:** Solitary exposure. The subject is displayed to everyone and isolated from everyone at the same moment, which is a very strong psychological contradiction.  
**Used for and where it works best:** A performance on stage, a public confession, the reckoning, and the dream where a character finds themselves alone. In musical and performance work it is the solo shot, and in drama use it as an interior image rather than as realistic lighting.  
**Best in:** formats: Concert / Live Event, Music Video, Feature Film, Drama Series Episode, Title Sequence / Opening Credits, Dance Film, Anime (Japanese 2D), Short Film, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Musical, Drama, Tragedy, Melodrama, Psychological / Arthouse, Surreal / Absurdist, Comedy, Shojo (anime romance)  
**Avoid when:** Outside a stage or a dream context it looks contrived. And a hard circle on the floor exposes the fact that nothing in the room could produce such a narrow source.  
**Prompt:** `a single hard follow spot from above isolating the performer in a circle of light, everything around it black`  
**Yields to:** `light.interrogation` — Outside a stage or dream, nothing could make that circle.  
`light.spotlight`

### Concert Backlight Beams

**Also called:** beam lights, moving heads, stage beams  
**What it is:** A row of moving fixtures behind the performer firing narrow hard beams toward the camera and moving with the beat, with haze making every beam fully visible.  
**Effect on the audience:** Energy, crowd and celebration. The beams turn the air itself into an element of the image, so the frame is full of movement even when the performer stands still.  
**Used for and where it works best:** The concert, the live stream and the music video, and the chorus beat. In sports advertising or a product launch it sells the feeling of a big event, and in vertical short-form one beam sweeping behind the subject makes a visual hook in the first second.  
**Best in:** formats: Concert / Live Event, Music Video, Vertical Short-Form (Reels, Shorts, TikTok), Commercial / TVC, Dance Film, Trailer / Teaser, Game Cinematic / Gameplay, Title Sequence / Opening Credits, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Musical, Action, Sports Drama, Sci-Fi, Cyberpunk, Adventure, Comedy  
**Avoid when:** With no haze the beams do not register and become mere spots of light. And aimed straight into the lens for the whole take they blow the image and lose the performer. Beams moving on the beat are repeated flashing toward the viewer: the rate and the stopping point are `safety.photosensitive_flash`, and this card sets neither.  
**Prompt:** `rows of narrow stage beams firing from behind the performer through heavy haze, beams sweeping with the beat`  
`light.concert_beams`

### Ring Light

**Also called:** ring flash, circular light  
**What it is:** A circular source surrounding the lens itself, so the light arrives from every direction around the axis, leaving a ring shaped catchlight in the eye and a thin even shadow all around the subject.  
**Effect on the audience:** Cleanliness, proximity and directness. The face reads flat and focused and the feeling is that the person is speaking to you personally.  
**Used for and where it works best:** Vlogging, short-form, direct to camera pieces and beauty and makeup video. In drama use it deliberately when a character is performing for an audience or manufactured for a screen, which is a strong signal in any story about social media.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Explainer, Commercial / TVC, Product Video / Motion Design, Corporate / Training, Fashion Film, Vertical Micro-Drama, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Comedy, Science / Educational, Drama, Psychological / Arthouse, Rom-Com, Dark Comedy / Satire, Slice of Life  
**Avoid when:** In any serious cinematic shot a ring light looks flat and cheap. The circular catchlight is a visible signature you cannot hide in the grade.  
**Colour temperature:** the screen row; most ring lights are adjustable across the whole daylight range, so the figure is a decision rather than a fact — `light.kelvin_reference`  
**Prompt:** `ring light directly on the lens axis, flat even light on the face, circular catchlight in both eyes`  
**Yields to:** `light.flat` — A serious cinematic shot; the ring signature cannot hide.  
`light.ring_light`

### Softbox Key / Source Size and Distance

**Also called:** softbox, source size rule, inverse square in practice  
**What it is:** The practical rule that governs the softness of any source: the larger the source relative to the subject and the closer it sits, the softer the light and the faster it falls off. The same box gives soft light at half a metre and nearly hard light at five.  
**Effect on the audience:** Controlling the falloff decides how much of the world around the subject exists. A big close source isolates the face in beautiful light and lets the background sink away.  
**Used for and where it works best:** This is the most useful practical dial you have: instead of changing the fixture, change its size and its distance. For a beautiful face bring a large box close, and for a realistic room push it back so it covers the whole space evenly.  
**Best in:** formats: Commercial / TVC, Feature Film, Drama Series Episode, Interview / Video Podcast, Product Video / Motion Design, Fashion Film, Music Video, Corporate / Training, Wedding / Event Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Romance, Drama, Comedy, Family, Science / Educational, Melodrama, Musical  
**Avoid when:** A very large source very close makes the background go completely black because the falloff is brutal, so if you need the background, add distance. And in a scene that needs harshness, too much softness reads as a lie.  
**Prompt:** `large softbox close to the subject, very soft wrapping light with rapid falloff, background sinking into darkness`  
`light.softbox`

### Lighting Change Within a Shot

**Also called:** in-shot lighting cue, live light change  
**What it is:** The lighting changes during the take itself with no cut: a lamp goes out, a curtain opens, the character steps into a pool of light, a cloud passes. The change becomes an event in the scene.  
**Effect on the audience:** The turn feels real because the viewer watched it happen. It is far stronger than cutting to a new image, because the eye registers the change without registering the reason for it.  
**Used for and where it works best:** The decision, the revelation, the arrival of a new character, and the end of a scene. In theatrical and dramatic work it is the most elegant way to change mood without music or dialogue, and in heritage documentary let the sun reach a carving during the take so the light reveals it for you.  
**Best in:** formats: Feature Film, Drama Series Episode, Short Film, Heritage / Historical Documentary, Music Video, Anime (Japanese 2D), Game Cinematic / Gameplay, Limited Series, AI-Generated Clip | genres: Drama, Thriller / Suspense, Tragedy, Horror, Romance, Heritage (civilisation-focused), Historical / Biopic, Psychological / Arthouse, Mystery / Whodunit  
**Avoid when:** If the change has no visible cause it reads as a technical fault rather than a choice. And if it happens too fast it reads as a camera error rather than as an event.  
**Prompt:** `the lighting changing during the take, a warm lamp switching off and cold window light taking over, no cut`  
`light.light_change`

### Reveal by Light

**Also called:** light reveal, lighting entrance  
**What it is:** Something has been in the frame from the start but sitting in darkness, and light is what reveals it: a door opens, a torch passes, a fire catches, a curtain is drawn. The camera does not move and the edit does not cut.  
**Effect on the audience:** A delayed shock. The viewer realises the thing was there the whole time and they never saw it, which produces a retroactive fear.  
**Used for and where it works best:** Horror and mystery: the figure standing in the corner, the body, the message on the wall. In heritage documentary use it on a relief or a statue so it emerges from darkness, and the reveal itself becomes a visual lesson about the place.  
**Best in:** formats: Feature Film, Heritage / Historical Documentary, Short Film, Trailer / Teaser, Anime (Japanese 2D), Game Cinematic / Gameplay, Drama Series Episode, Documentary Feature, AI-Generated Clip | genres: Horror, Mystery / Whodunit, Thriller / Suspense, Supernatural Horror, Heritage (civilisation-focused), Gothic / Vampire, Psychological Horror, Historical / Biopic, Folk Horror  
**Avoid when:** If the audience saw the thing before the reveal the idea collapses, so the darkness has to be real on set and not added in the grade. Repeating it in the same film simply trains the audience to expect it.  
**Prompt:** `a figure hidden in darkness at the edge of the room revealed as a torch beam passes over it, camera locked off`  
`light.reveal_by_light`

### Shadow as a Character

**Also called:** shadow presence, the shadow arrives first  
**What it is:** The character's shadow enters the frame or grows on the wall before the character does, or the shadow remains all we ever see of them for the whole scene.  
**Effect on the audience:** The threat becomes larger than the body. Imagination builds the character bigger than they are, and the viewer waits anxiously for the body that follows the shadow.  
**Used for and where it works best:** The entrance of the villain or the monster, the unwanted visitor, the king entering the throne room. In heritage work it is an excellent tool because it gives presence without showing a face, and in horror a large shadow delivers threat with no effects budget.  
**Best in:** formats: Feature Film, Heritage / Historical Documentary, Anime (Japanese 2D), Trailer / Teaser, Short Film, Game Cinematic / Gameplay, Drama Series Episode, Music Video, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Horror, Gothic / Vampire, Thriller / Suspense, Mythology / Ancient Epic, Heritage (civilisation-focused), Noir / Neo-Noir, Fantasy / Epic, Folk Horror, Supernatural Horror  
**Avoid when:** If the shadow shape suggests nothing legible you get mystery with no content. Using it for every entrance drains its value and makes the film look theatrical.  
**Prompt:** `a long shadow growing across the wall before the figure enters, the shadow much larger than the body that follows`  
`light.shadow_character`

### Shadow Play on a Wall

**Also called:** shadow theatre, silhouette play, hand shadow  
**What it is:** The action is told entirely as moving shadows on a surface, a wall, a curtain or tent canvas, instead of being shot directly, the way shadow theatre works.  
**Effect on the audience:** Abstraction and symbol. The viewer infers the action instead of seeing it, becoming a partner in the telling and drawing a wider meaning than the details would give.  
**Used for and where it works best:** A story inside a story, a mythic prologue, an act of violence you do not want to show, and a distant memory. In heritage work it is a beautiful way to narrate a battle or a legend without faces or blood, and in kids content it tells a tale in a gentle safe register.  
**Best in:** formats: Heritage / Historical Documentary, 2D Animation (Western / Cartoon), Kids Content, Feature Film, Title Sequence / Opening Credits, Short Film, Music Video, Anime (Japanese 2D), Experimental / Art Film, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography | genres: Mythology / Ancient Epic, Heritage (civilisation-focused), Fairy Tale, Fantasy / Epic, Historical / Biopic, Family, Preschool / Early Learning, Folk Horror, Tragedy  
**Avoid when:** Run too long it tires the viewer because there are no faces and no detail. And the shadows must read perfectly, otherwise they become shapes with no meaning.  
**Prompt:** `the whole action played as moving shadows on a stretched cloth, hard backlight behind the figures, shadow theatre style`  
`light.shadow_play`

### Eclipse Reveal / Backlight Turn

**Also called:** silhouette to face reveal, stepping out of the backlight  
**What it is:** The character starts as a black silhouette against a back light, then steps forward, turns, or a frontal source arrives, and their face is revealed inside the same shot.  
**Effect on the audience:** A move from symbol to human being. The viewer was imagining and now they see, so the reveal carries far more weight than an ordinary shot of a face.  
**Used for and where it works best:** The first appearance of a hero or a villain, and the return of someone who has been away. In heritage and epic work it is the ideal introduction shot because you keep the mystery and then grant the face at a single moment chosen by the director rather than by the cut.  
**Best in:** formats: Feature Film, Trailer / Teaser, Anime (Japanese 2D), Heritage / Historical Documentary, Game Cinematic / Gameplay, Music Video, Drama Series Episode, Short Film, AI-Generated Clip | genres: Fantasy / Epic, Mythology / Ancient Epic, Action, Heritage (civilisation-focused), Historical / Biopic, Superhero, Thriller / Suspense, Shonen Battle (anime), War  
**Avoid when:** Rush the reveal and you lose the stretch of mystery that gave the shot its value. And if the audience already knows the character, nothing is revealed and the device rings hollow.  
**Prompt:** `the figure begins as a full silhouette against a bright doorway then steps forward into the light and the face is revealed`  
`light.eclipse_reveal`

### Faces Hidden in Shadow

**Also called:** faceless staging, obscured face lighting  
**What it is:** Lighting designed so faces are never revealed: back light only, a head covering throwing a shadow, or the figure turned toward a distant source. Body, movement and dress are all visible; the face is not.  
**Effect on the audience:** The figure turns from an individual into a type. It stops being this man and becomes the priest, the soldier, the mother, carrying a collective meaning instead of a personal story.  
**Used for and where it works best:** Heritage and historical documentary whenever you stage a reenactment: hiding the face protects the work from claiming to know what a person who lived three thousand years ago looked like. In drama use it for the anonymous witness or the character you are not ready to reveal.  
**Best in:** formats: Heritage / Historical Documentary, Docudrama / Reenactment, Documentary Feature, Feature Film, Short Film, Drama Series Episode, News Report / Reportage, AI-Generated Clip, Generated Keyframe Feeding Video, Poster / Static Design, Portrait Photography, Headshot, Still Life Photography, Food Photography, Beauty Photography | genres: Heritage (civilisation-focused), Historical / Biopic, Mythology / Ancient Epic, True Crime, Thriller / Suspense, Drama, Faith / Biblical Epic, War, Mystery / Whodunit  
**Avoid when:** If every figure stays hidden for the whole piece the audience cools and loses sympathy, so build in moments where a face does appear. And hiding achieved by obviously contrived camera moves reads as evasion rather than style.  
**Prompt:** `strong back light only, the faces kept in shadow and never revealed, silhouetted figures in period dress moving through the space`  
**Yields to:** `light.eclipse_reveal` — The piece needs a moment where a face appears.  
`light.hidden_faces`
