In a standard three-point lighting setup, what is the light placed behind the subject to create separation?

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

Answer: (C)

Separating the subject from the background comes from a light positioned behind them to create a subtle edge along the silhouette. In a standard three-point setup, this back light sits behind the subject and aims toward the back and shoulders, so a thin rim of light appears around the outline. That rim helps the subject stand out from the background and adds depth, which a flat, front-lit look wouldn’t have. The key light provides the main illumination on the front, shaping features, while the fill light softens shadows on the opposite side. A hair light can also be used to highlight the hair, but the light behind the subject specifically for edge separation is the back light.
