Three-point Lighting

The most basic portrait lighting, lighting a person with three lights: key, fill and back. A key light 45° to one side of the camera shapes the face, a fill light 45° on the other side softens the shadows, and a back light behind the person brightens the outline of the head and shoulders, separating them from the background. It is the standard for classic narrative films and interviews, and since it only covers the person, the background has to be lit separately.

Lighting positions seen from above. Three lights: a key 45° to the camera’s left, a half-strength fill 45° to the right, and a back light behind the character.

Camera view. One side of the face is bright and a faint shadow remains on the other, while the ears and head glow from behind, standing apart from the dark background.

Casablanca (1942) · Source: Movieclips (YouTube) · Original video

Not to be confused with

Key Light: With only a key light, the far side of the face sinks into shadow and the outline gets lost in a dark background.
High-key: Raise the fill close to the key in three-point lighting and it becomes high-key. Three-point is a light arrangement; high-key is a level of contrast.
Low-key: Take out almost all the fill and it becomes low-key. A three-point arrangement can also make low-key.
