Check out this 1894 film prouced by Thomas Edison.
The film is hand tinted- a job that my own grandmother held years later in the 1930's. (A photo she tinted of my mother as a little girl sits on our mantle as I type this.)
Each frame was painted individually to make it appear that Annabelle's dress is changing color.
It truly is a beautiful art-one that requires a lot of patience.
From IMDB: "The Kinetograph would film at 48-frames per second. If that were the case for this 18-second film, there would be 864 frames where only the dress would be hand-painted."
