Tracking shot

This is a shot in which the camera moves parallel to its moving subject. This is usually a smooth shot in which the camera moves alongside ('tracking within') the subject, usually mounted on a dolly, in a side-to-side motion (relative to the scene or the action); also known as following shot; sometimes used interchangeably with dolly shot, pull back (pull-out, push-out, widen-out or push-back) shot, track back (moving away) or track in (or push-in) (moving forward), or zoom shot.
