Oh, wow fighting noise on multiple levels - that’s interesting and looks promising!
As soon as DT devs add support of cameras from RPU , I’d be able to try that too. thanks for advice!
So far, I use Lowpass with color blending, adjusting the radius per noise size (sometimes it’s different). I see that sensors are susceptible to low temperatures making the noise more pronounced.
That is not really how it works. The RPU samples are used for regression testing of rawspeed library.
For the camera support, one needs to open a new camera support issue. Just uploading samples to the RPU, while is immensely helpful, is not enough to get the camera supported.
That being said, please do keep submitting samples to RPU, there are still a lot of missing samples.
All new Samsung’s (NX3000+) are missing.
@Andrius Tried your method today and the results are amazing, even though I had no dedicated camera profile and used generic poissonian preset instead. Excuse the hastily applied mask to focus on the sky, but the results speak for themself!!!
@mosaster I am glad it worked for you.
I wish I could take a credit for this but I just copied somebody’s method.
I guess darktable devs have done a great job
Thanks for the NR presets. I’d modify them according to what houz suggests in this text:
“For profiled denoising better use ‘HSV color’ instead of ‘color’ and ‘HSV lightness’ instead of ‘lightness’”.
This is awesome!
My only real issue with DT was terrible noise reduction. Turns out it was just me being ignorant and didn’t understand the tool.
Thank god for that lol, I can now ditch Lightroom with confidence.
Some time ago I profiled my Fujifilm X-Pro 2 in accordance with the dt procedure and was surprised at the good (excellent) results obtained.
When I use either the ‘2-step’ or the ‘3-step’ (mentioned above ) option I see absolutely no difference from that produced from my single step usage.
Possibly it is my camera or the individual profiling … but I do like my simple results.
Probably I should have also mentioned … the X-Pro 2 is already well corrected for noise at ISO 800 by Fujifilm. Noise at that setting is not so different from the base200 setting. I do use that ISO 800 setting for 95% of all my imagery.
