Lighting an orange is a classic cinematography exercise, on or off the computer. Be sure to try this one yourself to get practice aiming and controlling Maya lights. This demonstration makes use of Key lights, Specular lights, Fill lights, Rims, Kicks, Fills, and Bounces, and shows how to aim and adjust each of them. Special issues to pay attention to are professionally naming your lights, testing your lights in isolation, and being able to exactly match a reference image with your lighting.
