Yes. I was using Local Laplacian LC because of M Pierre’s recommendation. But I do notice it very quickly applies an ugly ‘dark halo’ effect.
And I have noticed that Bilateral Grid LC does not do this — at all.
done - german is here: darktable 3: RGB oder Lab? Welche Module? Hilfe!
@anon41087856: Two things are unclear though:
Les modules qui travaillent en RGB linéaire et réalisent des opérations non-linéaires mais respectueuses de la chrominance (à condition d’activer le mode ad-hoc ) sont :
- courbes RGB ,
- niveaux RGB .
What does ad-hoc refer to?
Balance couleur :
- CDL : RGB_sortie = (slope × RGB_entrée + offset)^power
What does CDL stand for?
The english version on hackmd.io is also unclear about these.
Thanks - great article, great background infos.

Ad-hoc is latin for “designed specifically for that purpose”. RGB levels and curves can preserve the chroma provided you enabled their “chroma preservation” mode.
Colour decision list, aka slope/offset/power mode in color balance.

Thanks for quick explanation. I added that als footnotes to the translation.
It just occurred to me that you can do the following:
Turn off auto-apply basecurve and auto-apply sharpen in the presets
Create module presets auto applying filmic, tone equalizer etc.
Works fine………

Something else I’ve only just discovered that will significantly streamline my workflow…
It’s possible to create presets that are auto-applied to images but start off disabled. This means that you can override the default module settings but still enable those modules one-by-one. That way you can see the effect of each module in turn and tweak them at the right point in your workflow (without having to manually select a preset each time you move to a new module).
Just set set up the module as you like, disable it, then create your preset.
I knew you could do that with styles - didn’t know you could do it with presets.
Edit: Having used this on a few edits now, be careful because if you compress history stack and go back to an earlier stage, or reset the parameters, you’ll be back to the usual darktable defaults. I think it would still be nice (perhaps I’ll raise a feature request) to be able to change the actual module defaults so that they survive a reset and don’t appear in the history stack until switched on.

So… I see Rawtherapee 5.8 has Capture Sharpening, link. This is the sharpening that I have been looking for earlier in this thread, link.
Can DT do this, or anything roughly equivalent?
cheers

What if you moved them after filmic, which it is said outputs between 0 and 1?
Because after filmic, we are display-referred. Not scene-referred. The tone equalizer is designed to be scene-referred, and has an internal way of linearly scaling things back between 0 and 1 without applying any kind of non-linear transform. The filmic scaling is highly non-linear by design.
I was thinking of rgb levels and rgb curves since they can’t control values outside of 0-1, and filmic’s output is between 0-1. Having read your article, Darktable 3:RGB or Lab? Which Modules? Help!, I’ve stopped using those two, but reading this post, thought maybe there was a way to put them to work.
Thank you, BTW, for that article because I was lost before reading it.
