[edit] 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. 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.

This file is in the public domain in Russia. It was published before January 1, 1954, and the creator (if known) died before that date (For veterans of the Great Patriotic War, the critical date is January 1, 1950). Works belonging to the former Soviet government or other Soviet legal entities published before January 1st, 1954, are also public domain in Russia. (This is the effect of the retroactive Russian copyright law of 1993 and the copyright term extension from 50 to 70 years in 2004.) A Russian or Soviet work that is in the public domain in Russia according to this rule is in the public domain in the U.S. only if it was in the public domain in Russia in 1996, e.g. if it was published before 1946 (1942 for WWII veterans) and the creator died before that year, and no copyright was registered in the U.S. (This is the combined effect of the retroactive Russian copyright law of 1993, Russia's joining the Berne Convention in 1995, and of 17 USC 104A with its critical date of January 1, 1996.)
