Being desperate, I fired up Micrografx Picture Publisher 5.0a, an old Win 3.1 program. It's capabilities for doing color correction are quite powerful, even when measured by today's standards. Similarly to the Gimp it offers a dialog box for adjusting color curves, and in addition to manipulating points on the curve with the mouse, one can enter point coordinates with the keyboard. This is perfect for solving the problem I described in my original posting. Now, although Picture Publisher 5.0a is still a very nice tool, it does have a number of disadvantages, especially when it comes to handling modern file formats. Also, it - of course - doesn't run natively under LINUX. That's why I try to do more and more tasks with the Gimp, and that's why I still would like to hear about a simple solution for my problem with the Gimp. -- Felix E.
