dlRaw and auto contrast

Hi folks,

so in the background Jos and I are discussing how to handle the contrast problem... which contrast problem? Well when you open a RAW file without any filters it looks dull... When doing the same in UFRaw it looks contrasty... Of course we want a pleasing starting point for the processing so what to do?

When looking at the code, dlRaw seems to handle the gamma applied during all the conversions more "consistent" than UFRaw. At least I don't understand completely their procedure... But the drawback for dlRaw are dull images without any filter applied... We haven't settled this question for dlRaw completely, but after numerous tests I have now a RGB curve, which should do the trick... I have attached the file to this post, so just put it in your curves directory and set it as RGB curve in dlRaw... I could only test it with RAW files from my cameras, so please test with yours and leave feedback.

greets mike
