A single image in an animation sequence

is a hand drawn clear material representing a single animation frame. The material is usually celluose or Mylar.

(sometimes spelled cell) – Piece of acetate onto which a character is xeroxed or hand-inked, then painted with special cel paint. Cels are filmed on top of painted backgrounds to create the moving images you see on screen. Many studios, including Cosgrove Hall, have phased out cels in favour of computer animation. This means their value is increasing as fewer and fewer are produced.
