I am the one how does most of the darktable noise profile tickets in redmine. Accepting noise profiles is always a subjective process. Always attach the generated tar.gz file (without any modifications), it contains all the information that is required. I first look at noise_result.pdf mainly the “noise_levels” (for good fit) and “flat noise levels” (should be near the ideal line). For noise profiling only the green channel is used. Afterwards I look at the images if they are out of focus. For the images in the initial post i was not sure if I they are good enough. In my view there are better images like the one from elstoc as they have more pixels between over- and underexposed ones. Also profiling images could be more out of focus when using a tele lens, which have a smaller depth of field.
Only profiles from camera with original firmware will be added, also please do not modify presets.json file!
