Back Lights

Definition

Back lights are lighting fixtures used in video and film production to illuminate the subjects from behind, creating depth and separation from the background. They enhance the three-dimensionality of a scene and help to define the shape of the subject, making it visually distinct in a multi-camera setup. This technique is crucial for maintaining clarity in a scene, especially when multiple cameras are used to capture different angles simultaneously.
