Why is color photography of particular interest? Because this series of pix by Russian Sergei Mikhailovich Prokudin-Gorskii were shot in the year 1900. Kodak didn't produce Kodachrome film until 1935! Prokudin-Gorskii, who was the photographer for Czar Nicholas, shot pictures all over the Russian Empire using a technique whereby he took each photo three times, using red, green and blue filters in turn. The Library of Congress has digitally remastered the negatives, producing a stunning record of Russia at the turn of the century. Even better, the Library has made all 2,600+ photos available on the web!
