This little gem can be found on Kodak's Youtube feed. It's probably the oldest sample of color cinematography that most of us will ever see. There was plenty of experimentation with color in the early 20th Century, but the first feature-length color movie wasn't released until 1935 - 13 years after this test.
Early color film technology combined just two colors and didn't have anywhere near the range of what we have today but even in this primitive state, the celluloid image has something magical in it. I realize that part of this footage's beauty is in its age and antiquity, but there's something else to it too. There's a warmer, more natural feeling that I don't think you can replicate in digital. Absolutely gorgeous. I particularly love how the reds pop out at you.
