It seems to me that there isn’t ‘something wrong’ but ‘something right’. It used to be that the standard profiled de-noise was too strong for my taste and I had to back it off a bit to avoid losing detail or even use other modules, but now it ‘just works’ with default settings so I’m happy. There again I have changed camera, which might be something to do with it even though both cameras use the same sensor, but provided I’m at sensible (3200 or below) ISO values standard settings work brilliantly for me.

Hi list. Regarding this matter, from the discussion that took place, i could not conclude if there is in fact a problem with the denoise(profiled) module or is just poor use by my part. Any developments on the issue? Thanks in advance.

To: "darktable-users@lists.sourceforge.net<mailto:darktable-users@lists.sourceforge.net>" <darktable-users@lists.sourceforge.net<mailto:darktable-users@lists.sourceforge.net>> Hi all. I'm having some problems with the denoise(profiled) modules. I tried using the simple default module settings and the two instance approach described in the manual but i don't get better results using two instances. In fact i think it's quite the contrary. I've created a set of screenshots showing different results of different combinations of module settings on an image. They go from no noise reduction at all to simple default settings then having and instance for removing only choma noise, one for luma noise and then both. As an example, removing only chroma noise seems create even more noise. There's also a noticeable difference between HSV blending modes and "normal" ones. Shouldn't the HSV ones look nicer? Don't seem to... Am i missing something? Doing something wrong? The image was taken on a Nikon D7100 with the 18-105mm lens at ISO 1600. It has no other processing, except the default applied modules. You can look at the images here: https://goo.gl/gmkxMY Thanks in advance.
