A tracking shot is any shot where the camera follows backward, forward or moves alongside the subject being recorded. In cinematography, the term refers to a shot in which the camera is mounted on a camera dolly that is then placed on rails – like a railroad track. As a result, this type of shot is often referred to as a dolly shot. A handheld steadycam or gimbal may also be used for smaller scale productions. The camera is then pushed along the track while the scene is being filmed or moved manually when using a handheld rig.
