Hi - here is my first set of (de)noise data for the K-50. I hope I did everything right :) If not, let me know, and I'll do another set.

noiseprofiles: Add Pentax K-50

Fixes #10209


#1 Updated by Oliver Schumacher over 5 years ago

When I use the /tools/noise/gen-profile script to generate a noise profile, it says it injects the new profile in my darktable db and gives me a path to the new db. When it start darktable with this path, is the new profile supposed to show up in the denoise module, e.g. as "Pentax K-50", or is it still just a blank line (because that is what I get).
IF it should show up, the benchmark in the above posted profile data is rubbish and I'd have to redo it.

Well, the presets are generated. If you compile dt yourself you can also just add it to src/common/noiseprofiles.h and recompile.

However, many of the curves are not properly fit and thus the profile will probably nor produce good results. Could you try redoing the profiling with some new samples? Maybe with some larger bright areas?
