Q: What's "Three point lighting"?
A: It's a lighting setup that uses a light as a key light or your main source of light. Another for a fill light, you know, the light that illuminates the spots where the key light doesn't hit, to eliminate pitch black areas and simulate ambient or indirect illumination. And a rim light that is placed more in the back of the subject to create an outline that accents the subject's contours. Some artists approach creating the rim light effect using materials instead of lights! Three point lighting doesn't necessarily describe the number of lights involved but rather the aspects of the scene the lights illuminate.
