Hi Martin, I had read and have now reread the release notes https://github.com/darktable-org/darktable/releases/tag/release-3.4.0 and saw no mention of denoise modules being renamed. Maybe I am reading the wrong release notes? Previously there had been denoise bilateral filter and denoise non-local means and they seem to have gone but astrophoto denoise has appeared. Also, I tried to find the zone system and put it into one of my groups, but it does not appear in the search result when I am trying to manage my presets. I am using Windows 10 if this is relevant.

You can use zone system even it’s deprecated. You just need to put in into the group you want to find it. or access it by searching for it. Some further denoise modules weren’t removed but renamed - sometimes it’s worth to read release notes ..

While I much prefer the tone equalizer module over the zone system I feel having the choice to use or not use the zone system is best. What I really like about DT is the ability to have so many choices of modules to achieve your desired outcome. I can understand that modules may have to be deprecated if they can not be maintained or cause DT to not work correctly, but if this is not the case then I would agree that the zone system should be reinstated. I was also surprised to see some noise reduction modules have disappeared in the latest version of DT. I did like the options of multiple modules for tackling different noise issues. But in saying that I am impressed with the improvements to the denoise (profiled) module, especially the chrominance only preset in the hamburger. I really appreciate the effort of all the developers for producing my favourite editing program, but please only deprecate modules if you really have to.

I am still digesting them, but have made a lot of progress. I am using DT 3.2 so that I can compare zone system and tone equalizer. I understand that tone equalizer in v. 3.4 is a lot better, but I am putting off upgrading to it due to the lack of zone system. I took a sample picture to edit, with a good range of black to white. I want to make it look like the classic B&W street photography with "inky blacks". In zone system I pushed the dark shadows down toward the black to get this effect. I also pushed the highlights toward the whites, but not as much. There are 8 points on the zone strip that one can vary. I am going for the look of "inky blacks" over preserving all the detail. In tone equalizer using the default mask type of guided filter and spreading the mask histogram as much as I could, I got about 3.5 points on the curve that could modify the picture. I could not get anything near to the result from zone system. Too grey. I tried choosing 'no' in preserve details (in the masking tab), as Juan suggested. Now the mask spans all 8 EV and I was able to get very close to my picture from zone system. So my conclusions are 1. It is not certain that tone equalizer is mature since the last big update is only from late December. 2. If tone equalizer is not yet mature, it is premature to deprecate the zone system module. 3. The tone equalizer "preserve details" option of "no" that basically replicates the zone system/ tone curve is very buried. Maybe it should be on the simple tab. To be honest I find the tone curve hard to use and was initially smitten with the simple tab on the tone equalizer. 4. Learning the tone equalizer is much harder than the zone system (thank you for the hand holding). This is a barrier for beginners; let them get their sea legs using the zone system as they learn techniques that go beyond basic sliders. 5. Obviously in using the tone equalizer, there are other images where the intention is more of preserving detail while not adjusting tone values more than the detail mask allows. I can think of documentary cases like bird photos and scientific images. 6. The developers should keep the zone system in my opinion.
