Key Light
The Key Light is set to one side of the subject and above. This is the main light for the photo.
Fill Light
The Fill light is used to fill the shadows. As seen in the picture above, there are lots of shadows. For stock photos, a fill light is essential for the diffused type of lighting that stock photos usually have.
The lighting described is very basic. There are more advanced lighting techniques which require more lights.
Back Light
A back light is used to light the back of the subject and thus differentiate the subject from the background. It produces a somewhat “halo” effect.
Background Light
The background light is used to light the background.
Rim light
The rim light is often set up behind the subject and slightly higher than the other lights. Because this light is facing the camera, it's important that it be completely blocked by the subject or out of the field of view. If not you may get lens flare and lowered contrast
