Hello Everyone,
I guess this is more a color question than littleCms. Regardless, I'm
trying to understand the effects of black point comp on color "correctness"
for in gamut colors. Tried to come to a conclusion with test, but I get
mixed results.
The scenario is this. Rgb image has in gamut corporate logo and a photo
with both in and out of gamut colors. I apply relative colorimetric
transform with BPC and the photo improves with a great reduction in
clipping. However, the logo has now shifted as well and I can't say it's
less or more accurate. Meaning, is some test cases the deltaE with BPC was
larger and in others smaller.
Perhaps my tests are flawed. Tradition ICC, not device-link. So, would
the science of color suggest BPC would hurt "color accuracy" when applying
the relative intent?
Thanks,
Andrei
