This photo of the Nilov Monastery on Stolbnyi Island in Tver Oblast, Russia, was taken by Sergei Mikhailovich Prokudin-Gorskii in 1910 before the advent of colour photography. His process used a camera that took a series of monochrome pictures in rapid sequence, each through a different coloured filter. By projecting all three monochrome pictures using correctly-coloured light, it was possible to reconstruct the original colour scene. Photo credit: Sergei Mikhailovich Prokudin-Gorskii |
