With the limited (relative to CRTs) hardware controls on LCDs and the DDC
enabled two-way calibration options, I'm puzzled by the need for removing
the display profile from the loop when evaluating shadow and highlight
separation capabilities of LCDs. In Bruce Fraser's "black screen and curve
increase test" (RWCM page 215), I understand he is checking for optimal
black point setting, so it makes sense to send RGB values directly to the
display.
I want to give clients an objective way to determine if they are seeing
appropriate shadow and highlight separation in their images. I've got a test
file with 95-99%K patches over 100% and 1-5%K patches over 0%. Given that
with DDC-enabled software there is no fiddling around with black point or
bias controls, what exactly do I gain by having clients either softproof via
Monitor RGB or assign the monitor profile before making their evaluation?
Thanks.
