In the three-point lighting system, which light is typically the brightest illumination entering the scene?

• A. Back Light
• B. Key Light
• C. Fill Light
• D. Photo Reflector

Answer: (B)

In three-point lighting, the key light is the main source that shapes the subject and sets the overall exposure. It is positioned to provide the strongest illumination, defining the subject’s highlights and the main shadows, and it establishes the scene’s mood. The fill light is used to lighten the shadows created by the key, but it’s kept softer and less intense so the contrast isn’t flattened. The back light helps separate the subject from the background with a rim or edge of light, but it’s typically not as bright as the key. A reflector isn’t a separate light source; it simply bounces light into the scene, usually contributing less intensity than the key. So the brightest illumination entering the scene comes from the key light.
