Hello,
I made a custom Dartable noise profile for Nikon D40X in 2017 (2 years
ago) and did not use Darktable since that time until today. Today I used
it for real noise reduction for the first time. It seems to work well
enough, but I'm not an expert.
First a question: how to always have this profile available in
Darktable? I only know about running darktable as: $ darktable
--noiseprofiles "path/to/presets.json" Is there a simpler way that
adding "--noiseprofiles <...>" to CLI arguements?
Now, my profile for Nikon D40X. This URL [0] contains some downloadable
material: [0]: http://do1.nixtux.ru/download/darktable/ [1]
dt-noiseprofile-20170501.tar.gz - noise profile (Nikon D40X; if you like
it, feel free to include it into upstream if needed) [2] DSC_0131 -
DSC_0132.tif (is an HDR, combined DSC_0131.JPG and DSC_0132.JPG in
Hugin) [3] DSC_0131 - DSC_0132.tif.xmp - that HDR edited in Darktable
[4] DSC_0131 - DSC_0132.jpg - exported from Darktable, it contains
easily seen noise, e.g. on trees trunks, I did not apply this noise profile
