I first came across this photo series on “The Big Picture” at Boston.com a few weeks ago and it has been stuck in my memory since. It is a collection of photographs by Sergei Mikhailovich Prokudin-Gorskii (1863-1944) who undertook a photographic survey of the Russian Empire with the support of Tsar Nicholas II. The series of colour photographs took place between 1909 and 1912. Taken with a specialty camera, these photos are of stunning quality. I myself could not believe that they were taken a hundred years ago with such near-perfect colour quality. Visit the link provided to see the full collection.
