Lighting: Rim Lighting & High Key Lighting

Rim Lighting is a light placed behind the subject to create a subtle contrast between the setting and the subject the camera is focused upon. The rim light produces a three-dimensional look. You can use another light set to fill the subject from the front for an evening lit subject. Rim Lighting is often used to create drama within a photograph.

High Key Lighting is a bright light used to blow out most or all harsh shadows in an image. It uses multiple lights from different angles to achieve this effect. High Key Lighting is typically used to convey an upbeat or happy subject.
