Hi,
in a forum post I ran across this statement by Karl Lang:
1) A wide gamut LCD display is not a good thing for most (95%) of
high end users. The data that leaves your graphic card and travels
over the DVI cable is 8 bit per component. You can't change this. The
OS, ICC CMMs, the graphic card, the DVI spec, and Photoshop will all
have to be upgraded before this will change and that's going to take
a while. What does this mean to you? It means that when you send RGB
data to a wide gamut display the colorimetric distance between any
two colors is much larger. As an example, lets say you have two
adjacent color patches one is 230,240,200 and the patch next to it is
230,241,200. On a standard LCD or CRT those two colors may be around .
8 Delta E apart. On an Adobe RGB display those colors might be 2
Delta E apart on an ECI RGB display this could be as high as 4 delta E.
It's very nice to be able to display all kinds of saturated colors
you may never use in your photographs, however if the smallest
visible adjustment you can make to a skin tone is 4 delta E you will
become very frustrated very quickly.
Is the situation still the same? And what is the general opinion
about this issue here?
Thanks,
Markus
