In a standard 3 point lighting setup, which light separates the subject from the background?

• A. Background Light
• B. Back/Hair Light
• C. Key Light
• D. Fill Light

Answer: (B)

A light placed behind the subject creates a rim of light along the edges, which separates the subject from the background and adds depth. In a standard 3-point setup this back light (often called a rim light or hair light) is aimed at the back of the subject to produce that edge glow on the shoulders and hair. The key light is the main source that defines the facial shape, the fill light softens shadows on the opposite side, and a background light would illuminate the backdrop itself rather than help the subject stand out. So the light behind the subject is what most clearly separates them from the background.
