Homework assignment: Lighting

Rim Lighting: This is a technique that is used to give shape to objects in an image by backlighting the subject. When used as an effect, it gives the subject a lighted halo around them and a delicate look. It is most often used to define shapes against a background, but it can also be used to highlight subtle effects of a photograph.
