Snow white advancing technology

 Technicolour 

It emerged as a superior replacement for earlier problematic cemented printing methods. The process was principally developed by Daniel F. Comstock, one of Technicolor’s founders, and became one of the company’s most significant technological legacies, remaining in use for nearly fifty years until the mid-1970s.
 

The printing started with a blank piece of film.

• Dyes were pressed onto the film using a matrix relief for each color.

• The film and matrices were held together on a pinbelt, a 35mm-wide metal strip with pins/teeth along the edges to keep them aligned.

• The pinbelt was originally 240 feet long and formed a loop, requiring the printing machinery to be spread over several rooms.
• To compensate, Technicolor printed a “key image” underneath the color dyes. This was a soft or light black and white image that enhanced definition and contrast.
  

• This key image was an essential innovation to maintain visual sharpness in the final color print.

• animation technique where artist trace over livbe action footage frame by frame to make realistic footage
• origonally it was done by progecting film onto a glass pannel for tracing, now it is done digitally 
  

cels

typically movies had 24 cells per second in a movie, in snow white they they used a minimums of 192 thousand cells 

they use transparent plastic to create the illusion of movement 

used in the little mermaid and snow white 

used the same background just white different overlays, saved illustrators time 

24 fps 

multiplane camera, a vertical drop down camera that created 2d animation but it helps create depth and enhances realism 

each layer or plane represented a different depth of the scene being shot
