For most cameras, this would be the D65 reference. The scene-referred workflow for color images starts with the assumption that there are camera white bulb reference settings built-in to every digital camera. Please let's know if you have a view on how well 'denoise (profiled) non local means' is working for you with the K-3 Mark III. 'darktable -noiseprofiles ' to run darktable with the test profile file. It isn't necessary to have the new profiles included in a build of darktable to test them, as you can start darktable from a console/terminal window as per. There are instructions at and you need to use the darktable-tools-noise, which is probably included in most distributions. I spent a lot of time and effort generating those profiles, so I suspect another similar effort by me would more than likely produce similar results.Īnyone interested in having a try at generating a set of noise profiles for this camera? I provided the noise profile files for the K-3 Mark III to the darktable project. I should add that my images are typically in the range of 400-1600 ISO, and that I find 'denoise (profiled) non local means' gives cleaner results than the wavelets options. I don't think results from the 'denoise (profiled) non local means' are as clean as I typically get from K-1 images at the same ISO setting.

Anyone here been using darktable to post-process K-3 Mark III raw images?
