CIECAM02
How the effective contrast ratio will be reproduced in an workflow doesn’t
depends on the monitor alone. Also the lightning conditions of the room
is having a lot of influence on the effective contrast ratio of the monitor.
In a very bright en lighted room the effective contrast of the monitor
will not be the same like using the same monitor in the same room,
but without any additional light sources and closed curtains (e.g. dark
room).
One part of CIE Color Apperance Model 02 (CIECAM02) is to take care
about the luminance of the ambient light of the room. The monitors
gradation curve can be optimized to the luminance of the rooms ambient
light to optimize the effective contrast ratio (combination monitor and
ambient light) by choosing on of the CIECAM02 setting.
The NEC recommends to use one of the following settings depending
on luminance of the ambient light of the room:
0 - 32 Lux: CIECAM02 - dark
32 - 64 Lux: CIECAM02 - dimmed
>= 64 Lux: CIECAM02 - bright
The luminance and the white point of the ambient light of the room can
be measured with a measurement device which supports ambient light
measurements (e.g. basICColor SQUID 2 or X-Rite Eye-One pro).
