This little film test from Kodak is a sample of some of the earliest color motion picture film. For some reason, I couldn’t help but smile as I watched it.
“First tests on the Two-Color Kodachrome Process were begun in late 1914. Shot with a dual-lens camera, the process recorded filtered images on black/white negative stock, then made black/white separation positives. The final prints were actually produced by bleaching and tanning a double-coated duplicate negative (made from the positive separations), then dyeing the emulsion green/blue on one side and red on the other. Combined they created a rather ethereal palette of hues.”
