Should have gone to the list as well...

I have tested the new denoise module a bit more deeply today. I feel that there is something wrong with it. To me the denoise module does too much smoothing of the image and we are loosing lot of details. I'm wondering if this is not because it applies on the chromatic and on the luminance noises. The former is probably ok, but the later is often the cause of details loosing. In fact I'm able to get far better (read here something that is close to what LR4 does) results with the equalizer using only the chroma curve. Would it be possible for the denoise module to do something similar? Thoughts? PS: I know next to nothing about math on image processing.
Hello Pascal, can you give a little more insight what you did? Especially which camera and which profile you used. You are talking about denoised (profiled), right? I tried the new denoise (profiled) today with my Sony RX100, for which no profile is available. The results are indeed very bad, as expected if no profile is given. hal
