lighting
　
key-This is the main light. It is usually the strongest and has the most influence on the look of the scene. It is placed to one side of the subject so that this side is well lit and the other side has some shadow. this is a 3-point lighting technique. you only have one light on the main subject.

Fill- This is the secondary light and is placed on the opposite side of the key light. It is used to fill the shadows created by the key. The fill will usually be softer and less bright than the key. you could move the light further away to achieve this. You could also set the fill light to more of a flood so that the light spreads over a wider area.

Back-The back light is placed behind the subject and lights it from the rear. Rather than providing direct lighting its purpose is to provide definition and subtle highlights around the subject's outlines. This helps separate the subject from the background and provide a three-dimensional look.

High-key-this bright and diminishes contrast. high-key lighting doesn't require adjustment for each scene which allows the production to complete the shooting in hours instead of days. The primary drawback is that high-key lighting fails to add meaning or drama.

Rim-defines the outline of your subject and can take an image from dull and flat to eye-catching and dynamic. this is like back lighting but is placed looking straight at the lens of the camera.

chiaroscuro-defines objects without a contouring line, but only by the contrast between the colours of the object and of the background. using chiaroscuro lighting characters can be defined without colours
