These amazing color photographs were taken by Sergei Mikhailovich Prokudin-Gorskii between 1909-1912, as part of a photographic survey of the Russian Empire, sponsored by Tsar Nicholas II. To achieve these color photos, Prokudin-Gorskii used a specialized camera, which captured three black and white images in quick succession, each with a different filter - red, green and blue. These images were then combined and projected with filtered lanterns to show almost true color images.
