Your edit looks good. What settings did you do in sigmoid? Sigmoid didn’t look good in my hands for this image.
Personally, I don’t mind, I really like your edition. It highlights the details of the wall paintings.
I thought my edit was pushing colors and contrast to extreme… 
Sorry, I forgot, I added it to the post.
Thank you very much
I regularly use Sigmoid with two instances of the local contrast module, one for highlights and one for lowlights.
I also use the contrast equalizer and the DS module

It’s true that with the midi console, I tend to turn the buttons
Interesting, why two separate instances? What is the advantage?
I noticed that Sigmoid gives very nice contrast in the mid-tones, but easily loses details in the high and/or low lights. So I have two presets with parametric masks that allow me to adjust them separately.

Now I understand. I thought you were using the sliders in the module separately.

I like the way you recovered all the details of the fresco.

Original, playful, bizarre at least! 
Thank you.
BTW, I hadn’t noticed before that there’s a St. George killing the Drake (that’s me) in the fresco…
Here are two from the jpg using gThumb curve, then adding Uniform+curve+saturation. In the original, I originally saw the overpass as the side of a building next to the muraled ones, which need masking.

Never used gThumb as an image editing tool. Thanks for the tip.
Not sure where this will appear. I think Jean-Marc_Dignejmdigne’s fresco and my second underpass might show the most detail, if combined.

@anon42681393 For some reason gThumb is where I started going for psychedelic with curves.
It seems like an interface bug that replies to a reply go at the bottom of the page, and now I see a complaint about how I’m doing it.
Strict chronological order is how a forum works, that’s why its important to quote replies and use @'s to establish context @phobrain
