Is the colour distortion consistent? If so then than the negative of that tint could be applied to the images. http://www.imagemagick.org/Usage/color/#tinting If I had thousands of images to adjust, I would take out a handful, then play with a script using ImageMagick. A number of steps may be required. It could also generate some thumbnails. When done, it would make sense to keep the original scans secure. Even with careful planning, it would seem likely that at least a few images would benefit from a manual tweak, and that would be best done on the original image. -- Philip Stubbs -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
