Edge Light

Create a narrow line of light along the edge of a figure or object to separate it from the background.

Prompt

Use Edge Light: add a narrow controlled light from behind and camera-right that creates a thin bright line only along the light-facing outer hair, shoulder and coat edges of the original character. Keep the frontal features and clothing readable with subdued ambient exposure. Respect occlusion so the line breaks where an edge faces away; no uniform glowing outline, halo or added object.
