Below are some photos (cropped versions of the originals) by Sergei Mikhailovich Prokudin-Gorskii (1863-1944) who traveled through the Russian empire, which then included modern-day Uzbekistan, in the years 1909–1912. The photos in Khiva, Bukhara, and Samarkand were taken around 1910. Who knew they had color photography back then? Prokudin-Gorskii used an experimental color process which had apparently been invented in Russia.
