In three-point lighting, which light is typically the main source of illumination?

• A. Key light
• B. Back light
• C. Fill light
• D. Photo reflector

Answer: (A)

In three-point lighting, the key light is the main source of illumination because it provides the strongest, primary light that shapes the subject. Its placement and intensity establish the overall form, creating the key shadows that define features and depth. The fill light then slightly softens those shadows to control contrast, while the back light adds separation from the background by creating a rim of light around the subject. A photo reflector isn’t a light source itself; it just redirects existing light to fill in shadows. So the key light is the best answer because it sets the foundational illumination and sculpting of the subject.
