Dear Markus,
what is the general opinion here about ambient light correction that
some monitor calibration systems are offering?
I admit I have not seen one of these "smart" monitors in action. So
it's
unknown to me the degree of adjustment they can modify the monitor
luminance
with respect to ambient lighting. But it does not seem to me like a
useful
feature. To me, monitor calibration should be done for a certain
viewing
conditions and remain fixed from that point on. Usually, people are
after a
viewing booth setup that matches their monitor in luminance. Once
they found
it, I don't see why they would want a smart circuitry inside the
monitor to
alter the screen luminance to reflect ambiant lighing changes.
Sure it ensures, that
one is always able to distinguish between (0 0 0) and (1 1 1) but
then I am not able to distinguish between (0 0 0) and (1 1 1), as
defined in the output space, on a lot of printed material,
particularly on photographic material without illuminating it from
the back.
See above.
Are there any norms for this ambient light correction
The only "norm" I know with respect to ambient lighting in the
graphic arts
or photography is ISO-3664.
or is it
different from software to software?
Maybe the folks at basICcolor have a different idea?
Best,
Markus
