Color photos taken by Prokudin-Gorskii, a Russian photographer, in the late 1800s and early1900s in several countries. (Color film was not commercially available until the 1930s.)
Prokudin-Gorskii used a three-plate camera with black and white film, each film exposed through either a red, green or blue filter. Then he printed each film on a single piece of special color paper through the complementary filters of cyan, magenta and yellow, creating a color image on the paper. A tedious process that produces a color image that will last centuries and the B&W negatives also will last
that long for reprinting.
