Amazing what one can learn mere
Reading the dithering method man pages. That's really what I wanted. Cant
wait to try it.
And what a coincidence: the Hot Pixels method is explained right after
that.
Thanks again,

Great, Jo!
I've never understood the purpose of this method. Maybe now the time has
come for me to understand it.
(out of this topic, I've never used the HotPixels module before a couple of
weeks, when some photos shot at night, toward a source of light, showed 2
or 3 pixels, one red, another blu
right, this kind of artifact results from low bit depth even for
perfect images without noise reduction. ulrich wrote the dithering
module to counteract that:

might be helpful in your case, too.

This photo was saved in jpeg 100%, raw denoising of 0.004. I managed to get
rid of the majority of the bands, but you can see some lines above/around

Hello Johannes,
I was using Jpeg 97%
I use, normally, only the raw denoising, starting with 0.002 points, going
to 0.006 if needed and the image colors permit.
Experimenting with 0.004 raw denoising I can see some band even with the
PNG 100% export. But I admit it's better then at 97% jpeg.

I've been experiencing this behavior specially in sunset photos.
After applying the modules that I want, among them the sharpness module, if
I want to get rid of the raw noise, the exported jpeg shows bands on the
degrades parts of the image (sky, for instance, or dark areas).
