Film is the production of moving images

Film is an art form that finds expression in the production of moving images using photography, camera and sound technology. As a rule, the images are projected onto a screen in the dark using a film projector or generated on a screen. Nowadays, cinema and television films are mostly coloured images that are set to music and accompanied by music. The original word for 'filming' is cinematography (from the Greek kinema, movement, cf. kinematics and -graphy, 'to record'), the analogue of photography, 'sound recording'. From this word, the expression cinema 'film theatre' develops as a shortening (light play 'work of film art', this word also represents a contemporary formation of the early years of film into acting).
For the actors significantly involved in the production of a film - in particular screenwriters, directors, actors, cameramen, production designers, costume designers, film editors, sound designers and film composers - the film is also a means of artistic expression and cultural activity. Certain films, especially “author's films”, have now become an integral part of high culture and are reviewed and analysed from an art historical perspective like other artistic works. The artistic forms of film include, in particular, experimental film.
