Read up about Sergei Prokudin-Gorsky, if you want your mind blown. A Russian inventor hired by the Czar to photo-document the Empire, he worked 30 - 40 years before the photos in the article above. He developed a system of mirrors and filters to take three B&W photographs simultaneously in the red, green and blue spectrums. Originally, displaying them was only possible with a projector that super-imposed the three images. But computer processing allows the reconstruction of his photographs: https://upload.wikimedia.org/wikipedia/commons/e/e3/Rgb-compose-Alim_Khan.jpg https://upload.wikimedia.org/wikipedia/commons/e/e3/Rgb-comp... (That is Alim Khan, direct descendant of Genghis Khan, last of the Mongol rulers. Is your head spinning yet?)

(you can see colour errors here on the fringes of the clothing, due to timing being off with the 3 shutters of his photographic process because the subject moved!) I've never seen the early 20th century in the same light since I discovered him. His works are all in the public domain: https://commons.wikimedia.org/wiki/Sergey_Prokudin-Gorsky https://commons.wikimedia.org/wiki/Sergey_Prokudin-Gorsky
