The multiplane camera is a special motion picture camera used in the traditional animation process that moves a number of pieces of artwork past the camera at various speeds and at various distances from one another. This creates a three-dimensional effect, although it is not actually stereoscopic. Various parts of the artwork layers are left transparent, to allow other layers to be seen behind them. The movements are calculated and photographed frame-by-frame, with the result being an illusion of depth by having several layers of artwork moving at different speeds - the further away from the camera, the slower the speed. The multiplane effect is sometimes referred to as a parallax process. An interesting variation is to have the background and foreground move in ''opposite'' directions. This creates an effect of rotation. An early example is the scene in Walt Disney's ''Snow White and the Seven Dwarfs'' where the evil Queen drinks her potion, and the surroundings appear to spin around her. == History == A predecessor to the multiplane camera was used by Lotte Reiniger for her animated feature ''The Adventures of Prince Achmed'' (1926). Berthold Bartosch, who worked with Reiniger, used a similar setup in his film ''L'Idee'' (1932). The first multiplane camera, using four layers of flat artwork before a horizontal camera, was invented by former Walt Disney Studios animator/director Ub Iwerks in 1933, using parts from an old Chevrolet automobile.〔 〕 His multiplane camera was used in a number of the Iwerks Studio's ''Willie Whopper'' and ''Comicolor'' cartoons of the mid-1930s. The technicians at Fleischer Studios created a distantly related device, called the ''Stereoptical Camera'' or ''Setback'', in 1934.〔 Barrier, Michael (2008).

The most famous multiplane camera was invented by William Garity for the Walt Disney Studios to be used in the production of ''Snow White and the Seven Dwarfs''. The camera was completed in early 1937 and tested in a ''Silly Symphony'' called ''The Old Mill'', which won the 1937 Academy Award for Animated Short Film.〔(2001) Audio Commentary by Walt Disney and John Canemaker.

''The Little Mermaid'' was the final Disney film to use a multiplane camera, though the work was done by an outside facility as Disney's cameras were not functional at the time.〔(2006) Audio Commentary by John Musker, Ron Clements, and Alan Menken Bonus material from ''The Little Mermaid: Platinum Edition'' ().
