PriskriboSergei-Prokudin-Gorski-Larg (cropped).jpg	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

1. Download an archival tiff image of one of the three-color slides [1]]. (These are huge files, around 70MB.)
2. Open the file in Photoshop, copy the top image.
3. Make a new file, and make sure it is RGB format
4. Make the channels visible in the floating palette
5. Paste the top image into the Blue channel
6. Repeat the process; paste the center image into the Green channel, and the bottom image into the Red channel
7. 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.
