A film, also called a movie or motion picture, is a series of still images on a strip of plastic which, when run
through a projector and shown on a screen, creates the illusion of moving images. A film is created by
photographing actual scenes with a motion picture camera; by photographing drawings or miniature models
using traditional animation techniques; by means of CGI (Computer-generated imagery) and computer
animation; or by a combination of some or all of these techniques and other visual effects. The process of
filmmaking is both an art and an industry.
Films usually include an optical soundtrack, which is a graphic recording of the spoken words, music and other
sounds that are to accompany the images. It runs along a portion of the film exclusively reserved for it and is not
projected.
Films are cultural artifacts created by specific cultures. They reflect those cultures, and, in turn, affect them. Film
is considered to be an important art form, a source of popular entertainment, and a powerful medium for
educating or indoctrinating citizens. The visual basis of film gives it a universal power of communication.
Some films have become popular worldwide attractions by using dubbing or subtitles to translate the dialog into
the language of the viewer.
The individual images that make up a film are called frames. During projection, a rotating shutter causes
intervals of darkness as each frame in turn is moved into position to be projected, but the viewer does not notice
the interruptions because of an effect known as persistence of vision, whereby the eye retains a visual image for a
fraction of a second after the source has been removed. The perception of motion is due to a psychological effect
called beta movement.
The name "film" originates from the fact that photographic film (also called film stock) has historically been the
medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture,
including picture, picture show, moving picture, photoplay and flick. The most common term in the United States
is movie, while in Europe film is preferred. Terms for the field in general include the big screen, the silver
screen, the movies and cinema; the latter is commonly used in scholarly texts and critical essays, especially by
European writers. In early years, the word sheet was sometimes used instead of screen.
