How can rim lighting help separate a subject from a dark background?

Asked on Nov 19, 2025

Answer

Rim lighting is a technique used to create a clear separation between the subject and a dark background by illuminating the edges of the subject, creating a distinct outline. This is achieved by placing a light source behind the subject, often slightly off to one side, to produce a glowing rim of light around the subject's silhouette.

Example Concept: Rim lighting involves positioning a light source behind the subject to highlight the edges, creating a halo effect that visually separates the subject from the background. This technique enhances depth and dimension, making the subject stand out in low-light or high-contrast scenes.

Additional Comment:

Use a hard light source, like a Fresnel or a bare bulb, to achieve a crisp rim effect.
Adjust the light's angle to control the thickness and intensity of the rim.
Consider using flags or barn doors to prevent light spill onto the background.
Rim lighting is effective in both portrait and cinematic shots to emphasize subject contours.
