The three-point lighting system is a standard method used in visual media production to create an effective and balanced illumination setup. It involves three main light sources: the key light, which is the primary source of illumination; the fill light, which softens and fills in shadows created by the key light; and the back light, which adds depth by separating the subject from the background. This technique enhances the visual aesthetics and helps to convey mood and focus within a scene.
