Okay, so i tried to make a "Test to show v2". xcf, but choseing 32-bit integer instead of the 8-bit integer, and then following the same steps as before.
Then opening them side by side to compare on my monitors. It seems like it has fixed / migated the issue alot, and given a larger file size, wich is logical. Thx
"Banding", now i can sleep tonight (joke). It feels nice to find out why you had problems, and how to fix them.
I would still like to be able to reproduce what you did nidhogg. You worked in a 8-bit channel, and used G'mic anisotropic smooth filter.
**Tried to attach the .xcf file, but it was over 6 mb.
Edit KL. 21:30 2019.09.11:
Made a "Test to show" 8, 16 and 32 bit. Put them up side by side on my monitors, and the 8 bit very bad banding, the 16 and 32 bit looked ok.
So i think i am gonna make working in 16 bit my standard. Maybe even 32 bit, but the file size do go up quite a bit.
