Lighting Position

Lighting position is where lights are placed around a subject. Because position controls where highlights and shadows fall, you can work out where a light has been put just by studying the results it creates. A lamp placed beside someone's left cheek brightens that cheek and casts a shadow across the right side of their nose — that shadow tells you the light is on their left.

Scenes with more than one light

Most scenes use several lights at once, each adding its own highlight and shadow. A key light is the main, brightest one and a back light sits behind the subject. By untangling which shadow belongs to which light, you can identify where each one has been placed.

Spotlights, hard light and back light

A spotlight sends out a narrow, bright beam, producing a pool of light with strong shadows around it. Those shadows add depth, separating a performer from the background instead of leaving them looking flat.

Hard light comes from a small or bare source, so the shadows it makes have sharp edges. Aimed at a face, it carves dark shapes across the eyes, cheeks and jaw, which can make a character look severe or unsettling.

A back light is placed behind the subject, shining towards the camera. It is a lighting position, not a camera angle. It can outline hair and shoulders with a bright rim and throw a large shadow forwards, towards the viewer. With a bright background, it can even turn a figure into a silhouette.

Position as a technical code

Position is a technical code because it shapes meaning, not just visibility. A quiz show host lit by a bright key light with a back light behind looks confident and polished. A witness in a crime drama lit by hard light from one side, leaving half their face in shadow, looks threatening, so the audience distrusts them before they speak.
