I’m relatively new to Darktable and raw processing in general. I was testing it out on a challenging file today.
After using the Haze Removal module, I noticed excess colour noise, particularly in the centre of the image. Maybe I’m pushing this too hard or expecting too much from this module?
I intended on tackling this by using the Denoise Profiled module with wavelets and strength set to 1.
When I applied this, it seemed to mess around with the highlight reconstruction and color reconstruction on the sun. I tried applying the Denoise module with a parametric mask to exclude the brightest pixels, but for some reason, it seems to be ignoring this and applying the denoise to the whole image. I have also tried using a drawn mask to exclude the area with the sun to no avail.
Any help much appreciated!
Here is a screenshot with the denoise module disabled:
With the module enabled (look at the effect on the sun!):
Finally, here is the parametric mask, showing the sun is excluded from the module’s effect:
Any pointers, very much appreciated.
Here is a link to the raw and xmp if anyone can tell me what’s going on.
Go easy, I’m new to this!
PS: I’ve found this image particularly difficult to work on!
