Animation
is the process of creating the continuous motion and shape change[Note 1] illusion by means of rapid display of a sequence of static images that minimally differ from each other. The illusion — like in motion pictures in general — is thought to rely on phi phenomenon.
Animations can be stored or recorded on either analogue media, such as Flip book, motion picture film, video tape, on digital media, including formats such as animated GIF, Flash animation or digital video. To display it, a digital camera, a computer, or a projector are used.
Traditional animation
(also called cel animation or hand-drawn animation) was the process used for most animated films of the 20th century. The individual frames of a traditionally animated film are photographs of drawings that are first drawn on paper. To create the illusion of movement, each drawing differs slightly from the one before it. The animators' drawings are traced or photocopied onto transparent acetate sheets called cels, which are filled in with paints in assigned colors or tones on the side opposite the line drawings. The completed character cels are photographed one-by-one against a painted background by a rostrum camera onto motion picture film .
