Three-Point Lighting, Explained Without Jargon
Most studio lighting setups are variations on one simple idea: a main light, something to soften its shadows and a light that separates the subject from the background.
The idea
Three-point lighting is a standard method in theatre, film, video and still photography. Using three separate positions lets the photographer light the subject as they wish while controlling the shadows produced by direct light.
The three lights
- Key light. The main source, usually in front and to one side. It sets the mood.
- Fill light. Weaker, on the other side, to lift the shadows the key creates. A reflector can stand in for it.
- Back light. Behind the subject, aimed at the head and shoulders, to draw a thin rim that separates them from the background.
Build it one light at a time
- Turn on only the key light and get the face right.
- Add fill until the shadows hold detail but still have shape.
- Add the back light last, and only as much as you notice.
Start with what you have
A window can be the key, a white wall the fill and a lamp behind the subject the back light. The positions matter more than the equipment. For a one-light version, see portrait light from one window.
