The default Gamma value is actually 1 (we are talking exponents). No, I'm not promoting an iterative approach. If you are using an ICC profile to correct your scan, you have to stick with the gamma value that was used to create the profile (you can of course create a number of profiles for a number of Gamma values. If you are not using ICC profiles, I would use the preview capabilities of the fontend to create a visually good scan, and then use e.g. Gimp to make it a perfect scan. Karl Heinz
