Disney was the first animation company to use storyboards. There were implemented in the production of "Snow White" which was Disney's first full-length feature, made in 1937.
For "Pinocchio," made in 1940, animation cells were placed on panes of glass. There were set at varying distances from the camera to give depth to the film.
1955's "Lady and the Tramp" became Disney's first feature shot in CinemaScope. Wide screen format called for special considerations to fill the screen.
Ub Iwerks modified a Xerox camera to transfer drawings to cells, which eliminated the process of inking. This technique was used for "101 Dalmations" in 1961.
Disney Animation Studios first began using computer generated imagery in the making of "The Great Mouse Detective," released in 1986.
Disney used CAPS--a computer animation production system--for 1990's "The Rescuers Down Under." This allowed sketches to be colored electronically and eliminated cells in animation.
