Zooming increases or decreases the visual distance between the camera and the subject. This can be done either by using the ring for a manual zoom or the servo zoom for an automated zoom feature. This technique is overused because it is one of most the basic and easy techniques of videography. It allows the camera operator to achieve a different compositions without moving the camera. It is also a quick and easy way to achieve a closeup shot. Nauseous feeling the audience gets from the unnaturally zoomed image is easily forgotten when the shot is composed. As a general rule, this effect should only be used when purposefully intended to be included as a part of the story telling process.
