# Source Preservation

Use when an existing image, selected board item, product, person, packaging, logo, chart, or supplied visual must remain recognizable.

Preserve identity, silhouette, proportions, materials, colors, logo placement, approved text, category, and important surface details.

Vary only the dimensions requested by the user, such as camera, crop, scene, props, palette, lighting, format, or finish.
