[custom_adv] A film, also called a movie, motion picture, moving picture, theatrical film, or photoplay, is a series of still images that, when shown on a screen, create the illusion of moving images. (See the glossary of motion picture terms.) [custom_adv] This optical illusion causes the audience to perceive continuous motion between separate objects viewed in rapid succession. The process of filmmaking is both an art and an industry. [custom_adv] 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 and computer animation, or by a combination of some or all of these techniques, and other visual effects. [custom_adv] The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art of filmmaking itself.
