turn-of-the-century color

I've recently discovered the work of Sergei Mikhailovich Prokudin-Gorskii, a Russian chemist and photographer who developed a technique - in the early 20th century, no less - to produce color photographs.  He used a camera that took a series of three monochrome images, using red, green and blue filters; later, these images could be recombined and projected with filtered lanterns to show near-true color images.

Thanks to the Library of Congress (beginning in 2000), and photographer Walter Frankhauser and computer scientist Blaise Aguera y Arcas, we can now see composites of the original surviving negatives provided by Prokudin-Gorskii's heirs.  It's simply astounding...
