Color photography from the 1910s? Yep.
My sister in law, Mariana, who lives in Stockholm, sent me this link to a fantastic collection of color photos of Russia, created a century ago. The process of making these was laborious — multiple long exposures were shot through different filters. The resulting plates were projected through colored glass. When the images lined up, the result was spectacularly realistic color photos.
If you look at the shot of the group of children, where it was impossible to get everyone to hold still long enough to keep the images in register, you can get a visual idea of what was going on.
Thank you, ma belle belle-soeur!
