Film

Film is a term that encompasses creature motion pictures, the field of film as an art form, and the motion picture industry. Films are formed by recording images from the world with cameras, or by creating images using animation techniques or exceptional effects.

Films are artistic artifacts produced by exact cultures, which repeat those cultures, and, in turn, change them. Film is considered to be an main art form, a source of popular entertainment, and a powerful method for enlightening -or indoctrinating- citizens. The visual elements of cinema give motion pictures a common power of communication; some movies have become popular universal attractions, by using dubbing or subtitles that transform the dialogue.

Traditional films are made up of a sequence of individual images called frames. When these images are shown quickly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the iridescent between frames due to an effect known as persistence of vision — whereby the eye retains a visual image for a small part of a second after the source has been removed.

The beginning of the name "film" comes from the fact that photographic film (also called film stock) has historically been the primary medium for recording and displaying motion pictures. Many other terms be present for an individual motion picture, including picture, picture show, photo-play, flick, and most commonly, movie. Additional terms for the field in common include the big screen, the silver screen, the cinema, and the movies.
