This was a fun tutorial to make, because it incorporated a lot of techniques that I never knew and may never have found out about had it not been for the Prokudin-Gorskii images and their introducing me to the possibilities of color channels.
This is the last of the first three tutorials I'm putting up (April 2004), although hopefully there will be more in the future, particularly on cleaning up damage to the negatives. Even when those are finished, however, tutorial 3 will still be the final step before going to the printer (or the web), and should be done last.
The procedures here work equally well following either the first or second tutorials, depending on whether your target is web or print.
