15-1:

Classic studio lighting is a system in which uses three lights on the subject and usually one or more on the background.  It is often referred to as three-point lighting. 
1. Key Light - this is the main illumination which is similiar to a light or lamp fixture.  The end of the key light is commonly a spotlight. 
2. Fill Light - this is the filling of the shadows created by the key light.  It is used to reduce the cheek, lip, and neck shadows.
3. Rim (Back) Light - typically behind the subject of the frame.  Generally mounted on over-head clamps or stands.  
4. Background Light - Similiar to the key light, it is the light that would naturally fall on the walls or other background items.

Natural lighting is a more natural form of lighting as opposed to three-point lighting.  The key to this approach is using soft light.

One way to light a background is adjusting the intensity.  To do this, one must even out the light pattern by using a double screen positioned in the spotlight's filter holder.
