Traditional animation also called cel animation or hand-drawn animation or classical animation was the process used for most animated films in 20th century. The individual frames of a traditional animated film are photographs of drawings, which are first drawn on paper. To create the illusion of movement, each drawing differs slightly from the one before it. The animators’ drawing are traced or photocopied onto transparent acetate sheet 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 onto motion picture film against a painted background by a rostrum camera.
Rostrum camera is a specially designed camera used in television production and film making to animate still images or object.
The traditional cel animation process became obsolete by the beginning of the 21st century. Today, animator’s drawing and the background are either scanned into or directly into a computer system. Various software program are used to color the drawing and simulate camera movement and effects. The final animated piece is output to one of several delivery media, including traditional 35 mm film and newer media such as digital video. The “look” of traditional cel animation is still preserved, and the character animator’s work has remained essentially the same over past 70 years. Some animation producers have used term “tradigital” to describe cel animation which make extensive use of computer technology.
Example of traditional animation movies Pinocchio (United States 1940), Animal Farm (United Kingdom,1954), and Akira (Japan,1988). Traditional animated films which were produced with the aid of computer technology include The Lion King (United States,1994), Sen to Chihiro no Kamikakushi (Spirited Away) (Japan,2001), and Les Triplettes de Belleville (France,2003).
. Full animation refers to the process of producing high-quality traditional animated films, which regularly use detailed drawings and plausible movement. Fully animated films can be done in a verity of styles, from more realistically animated works such as those produce by the Walt Disney studio (Beauty and the Beast, Aladdin, Lion King) to the more ‘cartoony‘ style of those produced by the Warner Bros. animation studio. Many of the Disney animated features are example of full animation.
. Limited animation involve the use of less detailed and/or more stylized drawing and methods of movement. Pioneered by the artiest at the American studio United Production of America, limited animation can be used as a method of stylized artistic expression, as in Gerald McBoing Boing (US, 1951), Yellow Submariner (UK, 1968), and much of the anime produce in Japan.Its primary use, however, has been in producing cost-effective animated content for media such as television (the work of Hanna-Barbera, Filmation, and other TV animation studios) and later the Internet (web cartoons).
. Rotoscoping is a technique, patented by Max Fleischer in 1917, where animators trace live-action movement frame by frame. The source film can be directly copied from actors’ outlines into animated drawing, as in The Lord of the Rings (US, 1978), or used in a stylized and expressive manner, as in Waking Life (US, 2001) and A Scanner Darkly (US, 2006) . Some other examples are: Fire and Ice (US, 1983), and Heavy Metal (1981).
.Live-action/animation is a technique,when combing hand-drawn character into live action shots. One of the earlier uses of it was Koko the Clown when Koko was drawn over live action footage. Other example would include Who Framed Roger Rabbit (US,1988), Space Jam (US, 1996) and Osmosis Jones (US, 2002).
