# Relight

Adjusts the lighting of a product image — add dramatic shadows, warm fill light, studio lighting setups, or natural environmental light.

#### When to use it

Reach for Relight when the product is right but the lighting isn't — you want softer shadows, warmer tones, or a polished studio look. It's most powerful as the final step in a workflow: after rendering, applying patterns, and placing on a model, use Relight to give the image campaign-quality lighting.

#### How to use it

1\. Upload the product or scene image.

2. Dial in the lighting using the built-in controls: Light Direction (front, side, top, back, rim, or window), Light Style (soft or hard studio, natural daylight, golden hour, editorial dramatic, or e-commerce clean), Light Intensity (low, medium, high), Shadow Style (minimal, soft, natural, or strong), Background Behavior (preserve, adapt lighting, or white studio), and an Output Type preset (e-commerce, fashion editorial, catalog, luxury campaign, or studio flat lay). Add optional notes for anything more specific.

3\. Click Generate. Cost: 5 credits.
