1. Start in Darkness. Make sure there are no default lights, and there’s no global ambience. When you add your first light, there should be no other light in the scene.
2. Add your Key Light. The Key Light creates the subject’s main illumination, and defines the most visible lighting and shadows. Your Key Light represents the dominant light source, such as the sun, a window, or ceiling light – although the Key does not have to be positioned exactly at this source.
Create a spot light to serve as the Key. From the top view, offset the Key Light 15 to 45 degrees to the side (to the left or right) of the camera. From a side view, raise the Key Light above the camera, so that it hits your subject from about 15 to 45 degrees higher than the camera angle.
