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.
Thanks

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 ..

I would tend to agree with Tanya about keeping the zone system. 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.
Thanks Terry

Thank you all for the tips on using tone equalizer. 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.
