A quick-and-dirty tutorial on converting Prokudin-Gorskii photographs with Adobe Photoshop edit

1. Download an archival tiff image of one of the three-color slides [1]]. (These are huge files, around 70MB. Anticipate 45 minutes to an hour over DSL.)
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.
