I would also add that you might be able to reduce the amount of texture in the first place by scanning the photo at 0 and 180 degrees and averaging the results together (either with arithmetic or 50% blending). 90 and 270 degrees might also help--then you'd have compute the average of four images.

Be sure there is some sort of fiducial marks on your scan so you can precisely line them up after rotating.

Thank you both! I'll try the scanning trick first as the texture is pretty nasty Then the FFT filter. (When I was learning FFT in one of my Math courses in college- actually, sleeping thru it, heh- I didn't realize that someday it's come in this handy.) BTW, this is one of the friendliest boards I've seen- lots of friendly and beautiful people.
