Bob,

Remember that was your question. I know what to do when my eyeballs disagree
with measurements.

Well, not really, because the (classic) case I tried to illustrate was
between a monitor and its hardcopy counterpart. The areas being compared
correspond to about the typical 2 degree fovea centralis area for which all
critical color matching experiments are designed.

I'm surprised that Eizo states that "human vision is nearer a 20 degree
field-of-view"? I know I've heard of "rod intrusion", where 10 degrees is
sometimes used, but "20" degrees? Are you sure you haven't had too much
cappucino this morning?

Best / Roger
