A film, also called a movie, motion picture or photoplay is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession. A film is created byphotographing actual scenes with a motion picture camera; by photographing drawings or miniature models using traditional animation techniques; by means of CGI andcomputer animation; or by a combination of some or all of these techniques and othervisual effects. The word “cinema” is often used to refer to the industry of films and filmmaking or to the art of filmmaking itself. The contemporary definition of cinema is the art of simulating experiences to communicate ideas, stories, perceptions, feelings, beauty or atmosphere by the means of recorded or programmed moving images along with other sensory stimulations.
