[Jolly Amaranto]

Over 100 years ago there was a Russian chemist named Prokudin-Gorskii who was commissioned by the Tsar to travel the Empire and document it photographically. He developed a process for taking color photographs using black and white glass plates. He exposed three identical positive images on a glass plate through three different color filters, (yellow, magenta and cyan). The developed images could only then be properly view when projected overlapping through the same filters so the images all registered precisely on a screen. After the revolution he was exiled to western Europe and took his glass plates with him. Today the black and white images can be scanned into a computer with the colors added, the three images combined with a fourth image generated from the three originals in black to add shadows and all used to recreate the color scenes.
