This rare series of photos was taken 100 years ago in Tsar Nicholas II's Russia. The photographer took triplicate black and white photos, in quick succession, each with a red, green, and blue filter. The resulting color photographs seem incredible to modern eyes, trained to see the distant past in different tones.
I have to admit that, though I always knew it was ridiculous to imagine the past appeared any different to the present, these photos have a jarring effect on me. Remember that these were shot before the Russian Revolution, and the First and Second World Wars. The full series can be found HERE.
