Animation Cel: An animation cel is a painting on a clear sheet of acetate, usually 12.5 x 10.5 or larger. All cels are original paintings, not prints or reproductions. In general there are two kinds of animation cels: production cels and limited edition cels. (See below).

Production Cel: A production cel is a one-of-a-kind painting that has actually appeared in an animated film. The pencil drawing is transferred to the production cel, which is then hand painted. During filming, production cels are laid over a background painting and photographed in sequence. When the film is projected, the sequence of images creates the illusion of the cartoon characters in motion.

Limited Edition Cel: Limited edition cels are created expressly as fine art and have not appeared in a film. They portray the characters in classic poses or scenes from a favorite film. Each cel is hand painted, serial numbered and often hand-signed by the animator. The guaranteed edition sizes are small, generally 300 to 750.

Animation Drawing: Cartoon characters are brought to life with a pencil and paper. When the animator is satisfied that the sequence of drawings captures the action as intended, each drawing is transferred to a cel.

Storyboards: A series of sketches, similar to a comic strip, which outlines the action and dialogue in a scene. These drawings would be pinned up on a bulletin board as the story took place (Live action movies use storyboards as well).
