That seemed to work. And it looks like the i1Profiler matrix profile is not
more accurate overall, although it does a lot better on grays. It also seems
to miss in the opposite direction on some colors, which ends up being
subjectively "nicer", but not more accurate. So with ArgyllCMS, reds are too
orange, and with i1Profiler, they're too anti-orange, or something.
So it looks like if I want accuracy, I will have to use a LUT profile.
Now here's a new wrinkle... Both i1Profiler and ArgyllCMS seem to be producing
pretty accurate LUT profiles, but the one from i1Profiler looks a lot smoother
in Adobe Camera Raw and Photoshop, whereas the ArgyllCMS one has some pretty
ugly banding. Is there anything that can be done to get a smoother result? Use
a larger testchart? Smaller? Add some other magic ingredient?
