English: detail of the photograph "Po r. Karolitskhali" or "On the Karolitskhali River" showing Sergei Mikhailovich Prokudin-Gorskii as part of his work to document the Russian Empire from 1909 to 1915. Prokudin-Gorsky's camera design required a camera operator to take three individual negatives after each other. Given that Prokudin-Gorsky is seen posing in the image, it is more likely that one of his assistants took the picture.

A quick-and-dirty tutorial on converting Prokudin-Gorskii photographs with Adobe Photoshop
Download an archival tiff image of one of the three-color slides [1]]. (These are huge files, around 70MB.)
Open the file in Photoshop, copy the top image.
Make a new file, and make sure it is RGB format
Make the channels visible in the floating palette
Paste the top image into the Blue channel
Repeat the process; paste the center image into the Green channel, and the bottom image into the Red channel
View the whole thing. The channels won't be aligned; they'll need to be nudged with the Move tool. Work with the center of the image; magnify 200-300% for best results.
