Hi everyone
In the old Google NIK Sharpener-Pro-3 suite, there was a ‘structure’ slider. This worked perfectly in removing mottle and blobs from dslr astro-photos’ dark sky background.
Do we have anything in Darktable to mimic this?
Cheers,
Steve
Thanks for the links and yeah, some interesting viewing. I’m more deep-sky-with-a-telescope, but some interesting .xmp to see how the experts do it.
Anyway, I’ve a reasonable approximation and perhaps ‘mottle’ was not the correct description. Something like this.
Thanks again.
Hi
Yes, it removes the smaller grain but leaves the background with blotches. That in combination with the patch size, seems to get closer to G-NIK’s structure slider.
Still thinking.
Thanks again.
