A monitor profile as an RGB working space? I've seen this documented in
too many places (more than one anyways) to leave this alone. What is
the
logic (if any) in setting one's working RGB space to their monitor
profile? In the latest issue of NAPP's publication "Photoshop User"
one of
the authors recommends just that. I guess that's one way to get your
output to match your screen...limit the gamut of your file to what can
be
displayed on the monitor!
Email the author and ask what the logic is. By the way, what article
and author?
Am I off base or is this a huge faux pas in color management?
1. On a particular workstation, with calibrated and profiled display,
you can still get good output. There is a source profile used for
printing, and it's based on the display device. So from this
perspective it's not a problem.
2. Using Monitor RGB is the only way to get complete continuity between
Photoshop, ImageReady and a web browser. (Except on Mac OS with a
couple of web browsers which assume sRGB and do display compensation by
default.) For web graphics, it's not unreasonable to use this
3. If the color management policy for RGB is not Preserve Embedded
Profiles, then this unique display profile is not being embedded in
images and it will not be possible to preserve the color appearance of
the original. Its only chance of looking correct will be on a
particular display, the originating display setup.
I'd say that if the usage is for web graphics, then the use of Monitor
RGB is not an unreasonable setup. One could say using sRGB as the
working space is better, but then that raises other issues for which
there are good answers and not so good answers. But if the usage is for
serious photo work, sharing files where preservation of color
appearance is important, or archiving images, then at a minimum the RGB
color management policy needs to be set to Preserve Embedded Profiles
or I'd say that's not good advice. But again, while the recommendation
of Monitor RGB is debatable, if it's being embedded it's no
catastrophe.
