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

[darktable-user] dt 2.4.1 crashes

DT 2.4.1 on manjaro. Occasionally, I get DT crashes. It's always: 1. Start DT which returns me to the Lightable at the last images I did something to it. 2. I want to do more, press D which switches successfully to the darkroom 3. After a few seconds (I guess some processing) it crashes. When I

[darktable-user] denoise weakness

Hi, I take the latest postings about denoise issues as an opportunity to ask a few questions. I am a long term DT user. I have spend hours creating my own denoise profiles with several instances of profiled denoise in wavelet and local means. But when comparing with rawtherapee or lightroom I

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
