I never was able to get decent results from profiled denoise for Nikon D610. I
see artifacts all over the place at the pixel level. OTOH the other 2 noise
reduction modules produce good results. I select either one depending on the
photo.

Subject: [Darktable-users] (Newbie) noise reduction: start from JPEG
Hi everyone,
I'm new to both Darktable and photography in general, so I'm quite a bit
confused about the "recommended workflow".
I normally shoot in RAW+JPEG and try to live with the JPEG only (possibly by
just cropping the JPEG within Shotwell). This is because I just tend to get
carried away in an endless path of postprocessing...
For some selected pictures however I'd like to just work on the exposure, white
balance etc... to hopefully obtain some improvements.
However, as soon as I open the RAW .CR2 file in Darktable, I'm most often
presented with a much noisier version of what I have in the JPEG (especially
for high ISO, of course).
I tried with the denoise (profiled) plugin, which seems to find the right
profile for my camera and ISO value, but I'm really having a hard time getting
close to what I have in the JPEG produced by the camera. Either I have lots of
noise or the image is heavily posterized.
Any suggestion? It looks like there's no way to equal the noise reduction
algorithm implemented by the camera itself... Or am I missing something?
Of course my dream would be to be able to open a RAW file in Darktable which
looks exactly like the JPEG produced by the camera, and start tweaking from
there... But I'm afraid that'll always remain a dream...
Any hint would be highly appreciated!
Thank you!
Gerlando
