Back light

Definition

Back light is a lighting technique used in film and photography where the light source is positioned behind the subject, creating a visual separation between the subject and the background. This technique enhances depth, dimension, and visual interest, often resulting in a halo effect around the subject, which can evoke specific emotional responses and highlight their features.

Review Questions

• How does back lighting contribute to the overall aesthetic of a scene in film?
