I know that this topic has been discussed multiple times already, but I am still struggling with it. I am a long time darktable user. I have read multiple tutorials about noise reduction. Most of them recommend profiled denoising in one or the other way. What I am looking for is noise reduction in darktable without profiles and compare this to rawtherapee.
I tried this today again with rawtherapee 5.4 and darktable 2.4.4. As always when I try this rawtherapee gives good results with just the regular noise reduction while I struggle to get any decent result with DT and non-local-means noise reduction + raw noise reduction.
See this comparison. Left side is rawtherappe, right side is darktable:
I did not spend time on the color. So dont bother about the slightly different colors. This is only about the noise level.
Any idea how to improve the darktable result without using profiled denoise?
