When I apply the 'denoise (profiled)' onto a fairly raw image the results, on my data, look quite acceptable. I have been trying to see which modules that I am using are creating more noise than others.
In another test I have used the para. mask to eliminate some processing from sky areas ... it is a bit tedious but it appears to help. I still feel that the blue is the trouble-maker.
