What is the function of background light in video production?

The function of background light in video production is primarily to give setting information. Background lighting helps to define the scene in which the subject is placed, providing viewers with additional context about the location and environment. It enhances the visual storytelling by creating depth and dimension in the background, making the setting feel more immersive and realistic.

By illuminating the background, this type of lighting contributes to the overall aesthetics and can indicate the time of day, the mood of the scene, or even suggest cultural or thematic elements relevant to the story. For instance, a well-lit background can convey a warm, inviting atmosphere, while a darker, shadowy background can suggest suspense or tension. Properly executed background lighting can enhance the narrative beyond just the subject, allowing the viewer to connect with the scene on a deeper level.
