10-20

The first permanent color photographs were taken using the three-color-separation principle first published by physicist James Clerk Maxwell in 1855. Maxwell's idea was to take three separate black-and-white photographs through red, green and blue filters. This technique was used by Prokudin-Gorskii in this photo of Austro-Hungarian POWs.
