kick (or kicker) contributes to a portion of the shading on the visible surface of the subject, while a rim light only creates a thin outline around the subject without necessarily hitting the front (visible) surface of the subject at all. In theatre A three-point system in theatre can be used in a variety of ways to help set a mood of the character. By having bright key light, but minimal fill and back light, this will give the effect of anger, whereas if the scene is very brightly lit with little shadow on the actor, this can make the scene look very happy. Four-point lighting The addition of a fourth light, the background light, makes for a four-point lighting setup. The background light is placed behind the subject(s), on a high grid, or low to the ground. Unlike the other three lights, which illuminate foreground elements like actors and props, it illuminates background elements, such as walls or outdoor scenery. This technique can be used to eliminate shadows cast by foreground elements onto the background, or to draw more attention to the background. It also helps to off-set the single eye nature of the camera, this means that it helps the camera give depth to the subject.
