Définition et Signification de "three-point lighting kit"

What is a "three-point lighting kit"?

A three-point lighting kit is a classic setup used in filmmaking and photography to create well-balanced and flattering illumination. It includes three lights: the key light, which provides the main source of illumination and is usually positioned at a 45-degree angle to the subject; the fill light, which reduces shadows and softens the contrast by being placed opposite the key light; and the back light, which is positioned behind the subject to create depth and separation from the background. This combination ensures the subject is evenly lit, with clear details and a visually appealing appearance.
