Rembrandt lighting is a portrait lighting technique that uses three key elements: a primary light source, a secondary or reflected light source, and the triangle of light they create on the subject's face. The primary light illuminates one side of the face while the secondary light provides reflected light and shadows, resulting in a triangular glow that emphasizes the features.
