A 2x3 grid portrait lighting reference sheet showing six classic cinematic setups on [a model's face]: Zone 1 (top-left): Rembrandt lighting, key light 45° elevated camera left, fill light -45° camera right at 0.5x, dramatic triangular highlight on shadow cheek. Zone 2 (top-center): Butterfly lighting, key overhead slightly front, fill reflector under chin, small butterfly nose shadow, beauty editorial style. Zone 3 (top-right): Split lighting, hard key light 90° camera left, zero fill, half of the face cast in deep shadow, noir mystery aesthetic.
