Answer: (C)

The primary purpose of a key light in film production is to serve as the main illuminator of the subject. This lighting setup is crucial as it sets the overall exposure for the scene and defines the subject by highlighting their features and form. The key light establishes the mood and tone of the scene, creating a sense of dimensionality and focus that draws the audience’s attention to the primary action or element. In addition to its role as the main light source, the key light often works in conjunction with other lighting elements to create a balanced and dynamic visual composition. It is typically placed to one side of the camera to create depth through contrast, including highlights and shadows that enhance the visual storytelling.
