Procoudine-Gorsky's pioneering work in color photography is little known. Using his innovative technique of taking three identical photos with three different filters (red, green, and blue), he produced thousands of unique, striking images of pre-revolutionary Russia (1909-1915). With carte blanche from the Tsar, he traveled the empire teaching children with his photos, showing them its great variety of landscapes, cultures, and people. A century later, thanks to digital image processing technology, these unique archival images, previously viewable only by projection, can be printed at last.
