 Several years ago I saw a clip of the first Technicolor film
done in circa 1930 with Eddie Cantor. It was just as good
as any 35mm film done today. The colors were bright and vivid
and the whites were just slightly toward blue. The original
Technicolor process used a 35mm Mitchell camera with 3 film
gates, side by side, and a prism to seperate the received
image into three paths. A color filter was used in each
optical path to seperate the images into the primary
colors. Because of the optics and filtering greater light
and more consistant color temperature had to be used.
Prints were made using the three negatives using a step
printing technique and dye transfer. The negatives were
standard b&w stock.
