A little over a hundred years ago, the public first saw pictures of Russian spaces "in natural color," applauded their author - pioneer of color photography Sergei Mikhailovich Prokudin-Gorsky. From 1903 to 1916, Prokudin-Gorsky managed to take about three and a half thousand amazing color photographs, which made up his unique heritage. Actually, the plan of Prokudin-Gorsky, supported by Emperor Nicholas II, was much more global: to show Russia from the Baltic Sea to the Pacific Ocean. Known further events did not allow these plans to come true.
