I'm currently working on restoring some old family photos (tears/scratches, colourising etc). These photos were scanned from prints and some of them were on that textured card stock that was so popular back in the day. The result is that some of the photos have a grid of white dots or cross-hatched texture which ruins the photo.
Short of rescanning these photos (not possible in many cases) does anyone have any tips on how to eliminate this texture from the images ?
I have tried the Fast Fourier Transform plugin for Photoshop which seems to do a reasonable job but isn't able to remove the entire pattern. I'm not sure whether that's because I'm not using it correctly or whether its not capable of eliminating it properly.
I'll post an example later on when I have access to my files.
