“Around 1905, Prokudin-Gorsky envisioned and formulated a plan to use the emerging technological advancements that had been made in colour photography to systematically document the Russian Empire. Through such an ambitious project, his ultimate goal was to educate the schoolchildren of Russia with his “optical colour projections” of the vast and diverse history, culture, and modernization of the empire. Outfitted with a specially equipped railroad car darkroom provided by Tsar Nicholas II, and in possession of two permits that granted him access to restricted areas and cooperation from the empire’s bureaucracy, Prokudin-Gorsky documented the Russian Empire around 1909 through 1915. He conducted many illustrated lectures of his work. His photographs offer a vivid portrait of a lost world—the Russian Empire on the eve of World War I and the coming Russian Revolution. His subjects ranged from the medieval churches and monasteries of old Russia, to the railroads and factories of an emerging industrial power, to the daily life and work of Russia’s diverse population.”
