Fascinating early..very early 20th century color photos of Russia

Fascinating that color photography has been around that long http://www.pravoslavie.ru/english/80171.htm Some fascinating looks at the scenes and times when Russia still had a Czar. Gunner I assumed these had to be separation negative shots, and the river scene with the bands of red/green/blue waves clearly demonstrates that. They took 3 black and white photos through either red/green/blue or cyan/magenta/yellow filters, and then recombined them in some fashion. |
