Thanks for the response.
I am only trying to understand why there is so much insistence that linear light use more than 8 bits. Gimp 2.10 shows that linear calculations are possible in 8 bits and in perceptual color space.
Sure, there will be banding issues and histograms that look like hair combs of lost data, but more than 8 bits is not required to do linear light calculations.
I converted an 8 bit sRGB to 8 bit linear sRGB in Krita, and I got a message that linear is not supposed to be used in 8 bit. But that's the only way to get rid of the darkening effects from blurring in 8 bit. This subject is so confusing.
And I should say I absolutely love 2.10's new layer modes. 'Addition' layer mode doesn't automatically blow out the bright areas like it did in 2.8. The Floating point is my favorite because even if it blows out I can get the info back.
