Rembrandt Lighting

Rembrandt Lighting is a form of studio lighting characterized by a light pointed at a face at an angle so that one side is completely lit and only a portion of the other side of the face is lit. It can be done using a single light and a reflector or two lights to achieve a natural but still artistic look with little equipment. 

This is a typical but wonderful example of Rembrandt lighting. All of the right side of her face is lit and a small portion of her left side is lit. If only a single light and no reflector was used, it is unlikely that the left side of her face would be so visible. 

Using Rembrandt lighting, I made the image below, but with a different pose. The main light shone on her hair with a secondary light facing the wall to reveal her face and the background.
