Ratio The ratio in a finished film of the amount of film shot to the length of the final footage. Shot A single uninterrupted action of a camera as seen by a viewer (see Take). Shots are labeled according to the apparent distance of the subject from the camera: extreme long-shot (ELS) also called an establishing shot; long-shot (LS); medium long-shot (MLS); medium or mid-shot (MS); medium close-up (MCU); close-up (CU); and extreme close-up (ECU). Although distinctions among shots must be defined in terms of the subject, the human body furnishes the usual standard of definition: ELS, a person is visible but setting dominates; LS, person fills vertical line of the frame; MLS, knees to head; MS, waist up; MCU, shoulders up; CU, head only; ECU, an eye.
