Film 

a series of sequential photographic images, or frames, associated with a single subject and intended for reproduction on a screen.

In modern cinematography, the following classifications of films are used: feature motion pictures, television films, animated cartoons, newsreel and documentary films, scientific films, educational films, and amateur films. Other classifications correspond to thematic content (historical and adventure films and comedies), cinematographic and projection techniques (silent, sound, black-and-white, color, wide-screen, large-format, panoramic, stereoscopic, and multiscreen films), and projection duration (full-length and short films). Special-purpose films include microfilms, test films, advertising films, and souvenir films.

Most films are produced at specialized motion-picture studios by groups of artistic workers and technical specialists, who use a variety of cinematographic equipment while filming on the studio sets and on location. Films for scientific, technical, and educational purposes are often produced in the motion-picture laboratories of research institutes and educational institutions. Amateur films are usually made in amateur motion-picture studios at clubs, educational institutions, and enterprises, as well as by individual amateurs.
