The picture taken above uses what is known as beauty lighting. I like how the lighting gives her a soft glow. This type of effect produces very little shadows and was created by have a light directly in front of the subject and two behind her, as well as a reflector placed underneath her face.
The effect in this shot was created by having a single light focused on one side of the subjects face and a warm fill light (created with a reflector) on the other side. There are dark shadows in this shot creating a dark and mysterious effect.
