His priceless color photographs documenting the waning days of the Russian Empire before the First World War and the Russian Revolution are today some of the most prized possession of the United States Library of Congress. In the beginning of the 20th century, color photography was still in its infancy. It was the German photochemist Adolf Miethe, with whom Prokudin-Gorsky studied briefly the techniques, who greatly improved the three-color principle of color photography. Using a specialized camera developed by Adolf Miethe, Prokudin-Gorsky took three black and white images in quick succession, using red, green and blue filters, which were later recombined and projected with filtered lanterns to show near true color images.
