In a standard 3 point lighting setup, which light is the brightest?

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

Answer: (C)

In three-point lighting, the main light is the brightest because its purpose is to shape the subject and establish the overall exposure. This key light provides the strongest direction and contrast, defining the facial features and form. The fill light softens the shadows created by the key, but it’s kept less intense so contrast remains intentional rather than flat. The back light, or hair light, adds separation from the background and helps outline the subject, but its intensity is typically lower than the key’s. Foot candle is a unit that measures light level, not a light source, so it isn’t something that can be brighter.
