What does Key Light mean?

Key Light refers to the primary light source used in film, television, and photography to illuminate the main subject of a shot. The key light is typically the strongest light in a scene and defines the subject’s form by casting shadows and creating contrast. It is often positioned to one side of the subject to create depth and dimension. The key light is part of a three-point lighting setup, along with the fill light and backlight, to achieve a well-balanced and visually appealing shot.

Example:A cinematographer positions the key light to the left of the actor’s face, creating dramatic shadows that enhance the emotional tone of the scene.
Example: The photographer uses a key light as the primary light source for a portrait, positioning it at a 45-degree angle to achieve a flattering, natural look.
