There are layers that are images that I imported (in my project that was set in 32 bit), but the 2 layers that are active in my screenshots are basically new layers that I created (Add Layer) and "Fill Foreground Color" them, so I'm guessing those really should be in 32?
Thanx for the tips, I will try that out tonight!
Best,
Stephane
You display is 8 bits (or 10 bits at most, but I don't know if Gimp 2.10 supports these), so even with 32 bits, you have have "banding". Banding happens because due to a "slow" gradient, the value of pixels abruptly changes along a line. Our vision has evolved to detect such features and we see lines even if the values are close (and due to gamma correction, this is even worse in the dark areas).
If you look at this image, you clearly see the line in the middle, between the #404040 on left and the #414141 on right:
Adding noise (RGB noise, Luminosity noise, or Spread noise ) you can spread the value change a bit to make it less noticeable. For the same purpose ypu can also use the "Dithering" option in the Blend tool.
Thanx Ofnuts,
I actually wanted to add Noise when I was done anyway, and it sure does the trick. All good, thanx to you both!
