Between 1909 and 1912, “photographer Sergei Mikhailovich Prokudin-Gorskii (1863-1944) undertook a photographic survey of the Russian Empire with the support of Tsar Nicholas II. He used a specialized camera to capture three black and white images in fairly quick succession, using red, green and blue filters, allowing them to later be recombined and projected with filtered lanterns to show near true color images. The high quality of the images, combined with the bright colors, make it difficult for viewers to believe that they are looking 100 years back in time – when these photographs were taken, neither the Russian Revolution nor World War I had yet begun.”
These images are now owned by the Library of Congress, which acquired the glass plates in 1948. Digital reproductions are available online.
