A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images usinganimation techniques or visual effects. The process of filmmaking has developed into an art form and industry.
Films are cultural artifacts created by specific cultures,which 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 method for educating – orindoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by usingdubbing or subtitles that translate the dialogue into the language of the viewer.
Films are made up of a series of individual images called frames. When these images are shownrapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to 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. Viewers perceive motion due to a psychological effect called betamovement.
The origin of the name "film" comes from the fact that photographic film (also called film stock) has historically been the primary medium for recording and displayingmotion pictures. Many other terms exist for an individual motion picture, including picture, picture show, moving picture, photo-play and flick. A common name for film in the UnitedStates is movie, while in Europe the term film is preferred. Additional terms for the field in general include the big screen, the silver screen, the cinema and the movies.
