Re: [darktable-user] denoising problems

Bill, thanks for letting us try your noise profiles. I did some quick tests, and they seem to work very well, particularly for very noisy images. On 03/10/2018 07:35 PM, William Ferguson wrote: I usually shoot 1000-1500 images per game (football, soccer, basketball), and 600-800 for baseball

Re: [darktable-user] denoising problems

I usually shoot 1000-1500 images per game (football, soccer, basketball), and 600-800 for baseball and softball. I shoot raw because of the stadium light problem. I'll shoot a burst and get 3 too green, 2 just right, 3 too red, 1 just right... I shoot with a Canon EOS 7D, a camera not renowned

Re: [darktable-user] denoising problems

I am finding that the 'denoise (profiled)' when switched from NLM to wavelets is doing a fairly good job in particular on my sky areas it is a bit aggressive but can be toned down as needed. On 03/10/2018 05:34 PM, Robert Krawitz wrote: > On Sat, 10 Mar 2018 17:04:45 +0100, David

Re: [darktable-user] denoising problems

Sometimes there are problems with a particular channel. I have had this kind of problem also with the blue channel (not the sky= in some specific conditions where there are few data on the blue channel and the white balance / colour balance tends to lower it even more. In this case, you can ends

Re: [darktable-user] denoising problems

Your examples interest me since they are shown on a blue subject. My experience with a fully profiled sensor is that the 'basic' Denoise (profiled) works quite well by itself EXCEPT for blue sky areas. My sky areas tend to form into rosette clumps whenever some reasonable degree of processing is

I took the profile Denoise_chinese from https://dtstyle.net/ Some times I simply rely on it while others I only tweak the demosaic module to VNG4 two times full average or Amaze. I should say however that I very rarely shoot at more than ISO 6400. Never compared to RawTherapee... I had a

Re: [darktable-user] denoising problems

Hey, denoising in darktable is somewhat tricky: Use the *denoise (profiled)*, set it to "wavelet" and set blend mode to "color". This eliminates the awful color noise. Use a *second instance* of denoise (profiled), set it to non-local means and choose blend mode "lightness". With that second
