These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it.

Recording and transmission of film.

• Recording and transmission of film.

The moving images of a film are created by photographing actual scenes with a motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects.

Before the introduction of digital production, series of still images were recorded on a strip of chemically sensitized celluloid (photographic film stock), usually at the rate of 24 frames per second.

The images are transmitted through a movie projector at the same rate as they were recorded, with a Geneva drive ensuring that each frame remains still during its short projection time. A rotating shutter causes stroboscopic intervals of darkness, but the viewer does not notice the interruptions due to flicker fusion.
