Sergei Mikhailovich Prokudin-Gorskii took most of these images between 1909-1912 in Russia. The Library of Congress purchased the glass plates in 1948, and through a process called digichromatography, allowing color images to be produced.. Prokudin-Gorskii projected his slides through three filters – red, green and blue on a device that was called a ‘magic lantern’ which superimposed the images onto a screen resulting in the color photo.
Read more about the process here and search the collection on the LOC site here. Pretty wild.
