On the photo fragment above: "On the river Sim at the station Ashi-Balashovskaya", 1910. Looks like a painting!
Fragment of the photo "Floodgate on the third verst from Shlisselburg", 1909. Boat "Zarya" by which Prokudin-Gorsky travelled along the Staroladozhsky canal.
Fragment of the photo "The main building of the monastery" Nilova pustyn", 1910
Fragment of the photo "The mill near Luga", 1905. By the way this mill served as a power plant as well!
