A light stage is an active illumination system used for shape, texture, reflectance and motion capture often with structured light and a multi-camera setup.

The multiple-camera setup, multiple-camera mode of production, multi-camera or simply multicam is a method of filmmaking and video production. Several cameras—either film or professional video cameras—are employed on the set and simultaneously record or broadcast a scene. It is often contrasted with a single-camera setup, which uses one camera.
