Summary:

• Physical light rays travel from the light source to the viewer/camera.
• By reciprocity, we may trace rays from the camera back to the light source.
• Directional light source has parallel rays.
• Light intensity decreases as a surface turns away from the light source.
• Three point lighting combines key, fill, and rim lights to provide the main, ambient, and accent lighting in a scene.
