Shot (filming)

In filmmaking and video production, a shot is a series of frames, that runs for an uninterrupted period of time. Film shots are an essential aspect of a movie where angles, transitions and cuts are used to further express emotion, ideas and movement. The term "shot" can refer to two different parts of the filmmaking process:

The term "shot" derives from the early days of film production when cameras were hand-cranked, and operated similarly to the hand-cranked machine guns of the time. That is, a cameraman would "shoot" film the way someone would "shoot" bullets from a machine gun.

Shots can be categorized in a number of ways.

The field size explains how much of the subject and its surrounding area is visible within the camera's field of view, and is determined by two factors: the distance of the subject from the camera ("camera-subject distance") and the focal length of the lens. Note that the shorter a lens's focal length, the wider its angle of view (the 'angle' in wide-angle lens, for instance, which is "how much you see"), so the same idea can also be expressed as that the lens's angle of view plus camera-subject distance is the camera's field of view.

(Caution: In this context, the focal length value differs with each film gauge and CCD size for optical reasons, but the angle of view is the same for any of them, so it's easier comparing the angle of view with lenses for different formats than their focal lengths. The same angle of view always gives the same field size at the same camera-subject distance no matter what format you're using, but the same focal length does not. For in-depth information behind the laws of optics regarding the influence that focal length and different formats have on field sizes, see 35 mm equivalent focal length, crop factor, image sensor format, and Digital photography: Sensor size and angle of view.)
