I would like to thank a lot Vyacheslav, who sent me a kind reply to my e-mail, aswell as permission to non-Russian member to join forums about this wonderfull project! I don't understand Russian, but Google translator does quite a good job, so it will be perfectly fine if you answer in Russian!
(also, I hope I chose correct board, not to spam the boards which are devoted to P-G)
To give you a short introduction of myself, I am big fan of Prokudin-Gorsky and early colour photography from Czech Republic. My main interest is history as whole, but I definitely love "Belle Époque", which basically covers the era when P-G was active in photographing.
I will try to devote to this project with at least the limited possibilities I have, but I already have found several photos for comparisons, old postcards, which I plan to post soon!
