Back light: rim light and subject separation

Rim light outlines the subject and “cuts” them out of the background. Darker backgrounds and brighter rims increase separation; bright backgrounds soften the effect.

Key points

Balance rim vs key for half-silhouette vs full silhouette
Flare can be embraced or suppressed—changes sacred vs documentary tone
Hair light often sells the rim on dark hair

Director logic

Hero entrances, divine hints, lonely backs—when the face goes, posture carries emotion.

AI prompts
