Did you know that the first color film wasn’t invented until 1935? Before that different photographers had to find ways to add color to their photos. For some it meant hand coloring the photos, but for one Russian fellow, Sergei Mikhailovich Prokudin-Gorski (say that 10 times fast, I dare you, oh and only with your best Russian accent!) figured out how to use color filters over his film to take 3 simultaneous exposures. The resulting black and white images could then be layered together to create a color photograph. It is really amazing seeing the photos he took as he traveled across Russia documenting the people and things he saw with his specially made camera.
Note that if you see red and green separation in his photos, they are not anaglyphs – its just where the images did not get lined up perfectly during processing. So your red and green glasses for viewing old 3D movies won’t help you.
You should really check out some of the photos here.
