jan 1, 1922 - 1922 - Williams Process

Description:

Williams Process was first used in the film "Beyond the Rocks", which until 2003 was lost. After years of experimentation, Williams had perfected a version of luminance keying that used a forground shot against black or white to produce a matte that would allow any background to be added behind the original scene. Up until this time effects shots were cut quickly so the audience didn't have time to see the flaws. However, Williams work was so refined it allowed for effects shots up to 30 seconds
