wow, three denoise steps. Does take some computing time ;-). I use two: #1: wavelets, strength: 0.25, blend mode: color 95% #2: non-local-means, strength: 1.0, blend mode: lightness 40% - 50% I did some tests some time ago and found these settings (and this order) o.k. though it slowed down the performance quite a bit. Not sure whether the order changed much, but i.m.o. it makes sense to get rid of the color-noise first and smooth the result afterwards a bit. But that's just trial and error here. Would be interested in the opinion of someone with some insight knowledge too :-) Regards, Felix > >> In the exact order you see in the right sidepanel, from bottom to top. >> >>> I have the following scenario: >>> >>> I apply the profiled denoise module 3 times.
