A friend sent me a link to some amazing scans of some colour photos taken by one Sergei Mikhailovich Prokudin-Gorskii in Russia. So what? Well, they were taken almost 100 years ago. The site explains more about the technology that was used to create them, and is also offering prints of the ones that have been scanned so far.
This is an amazing collection, not just because of the technology used to take them, the outstanding scanning and restoration work that Alex Gridenko has done, or even that they are colour photos of a time before most colour photos but because the many of the photos themselves are really stunning.
