I just did some *very* quick tries and have the following observations:
- Speed :-( It's not very fast ...
- Sharpening looks *great* in image parts with lots of details
- Color noise is sharpened too much with a sharpening setting of 3+ for ISO100 or 2+ for ISO1600. Maybe some more selectable parameters are needed here (like radius and threshold in USM)? Or include some logic with modifies such parameters based on the ISO?
Psssst! Schon vom neuen GMX MultiMessenger gehört?
