That would be interesting! It would put UFraw one step ahead of some of its commercial contemporaries. > Maybe I am not so skilled but threshold was always introducing nasty > artifacts.

Either way, it is my problem, not ufraw's > ;) I agree that it would likely affect some images negatively, just like the Sharpness slider in my camera tends to emphasize noise more than anything else at high ISO. But that's true of all sharpening methods used in all RAW processing software. I guess I'm spoiled by my camera's exceptional shadow range. I can pull a lot of detail out of some heavily under-exposed shots with minimal noise, even at ISO 1600-2000. ISO 2500 and higher is pushing it. The point is, I'd love to see this feature added to a future version of UFraw, and I'd love to see it done better than on the commercial alternatives. -- Frank Gore Project Manager www.projectpontiac.com ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
