This document provides an introduction to different lighting techniques used in filmmaking. It discusses three-point lighting, which uses a key light, fill light, and backlight. High-key lighting uses more fill light and results in a brighter, more even effect, while low-key lighting uses less fill light and creates darker shadows. Backlighting illuminates subjects from behind, creating a glowing halo effect. Additional lighting setups covered include four-point lighting with a background light, top lighting from above, and under lighting from below. The document provides examples of how different lighting techniques can be used to convey mood, setting, and intensity in a film scene.
