I was rather surprised to learn that the preset
for the world of print is set to D50 and 1.8..........for the last two
or three years I thought that we were being advised by the colour gurus
that unless we were using an Apple badged CRT screen, we would get a
better match to proof by using D65 and 2.2 allowed a better assessment
of shadow detail. Oh well it seems Sony have different ideas.
I've done some crude experiments with D50 vs. D65 and basically what
I've come up with is if you are in a low ambient light environment, D50
works better. If you have a window letting in daylight into your work
environment, or you take frequent trips outside, including using
outdoor light as your viewing booth, D65 works better. The reason is
chromatic adaptation. In the low ambient environment, your visual
system adapts to D50 better than D65 because rods (which don't sense
color, and are associated with low light vision including night vision)
are sensitive to blue light in low light situations. With daylight
streaming in, your visual system doesn't adapt well to D50 because it
is being asked to deal with two very different light sources, and
prefers daylight (running home to momma in a way).
When I block out my environment from daylight, I can use D50 quite well
in a few days. Initially it looked painfully yellow to me. When I went
back to D65 it was almost painfully too blue, but then I unblocked the
window (yeah I know I'm a heretic) and all was better.
As for the gamma, flip a coinor do the gamma test on page 218 of RWCM
(but make sure you see the tip on page 215 to make sure you've removed
the display profile from the loop.)
