I was going to say, what if I open up a CIE Lab Macbeth ColorChecker image?
Then convert to MonitorRGB. Assume MonitorRGB = crappyRGB. A cheap 9300K
laptop profile slapped on a beautiful Quatto monitor.
In principles, the ColorChecker 24 patches colors ought to look crappy, all
of a sudden, because they were converted to a color space that does not
match the monitor they are currently being viewed under, right?
At that point, convert from crappyRGB to the freshly measured ICC profile,
characterization only.
That characterization should new represent crappyRGB, right?
So, converting from crappyRGB to freshlyMeasuredRGB ought to make the
ColorChecker 24 pages match again.
Makes sense?

I am teaching a class in a lab full of WinXP PCs -- it's not so bad, really.
But, because of the school's tight security policies, because of the
internet and what not, they don't give anyone access to changing the
system's monitor profile around. I can use iMatch, ProfileMakerPro,
dispcalGUI all I want, but none of the applications are granted the right to
save monitor profiles at the end of their little routine, as they would
usually do. Currently, the way Photoshop color management is designed, there
is no way to be able to coerce Photoshop into choosing a monitor profile of
our choosing, in lieu of whatever can be found in either the Registry, on
Windows, I believe, or the System Profile, on Mac OSX.
Would there be a way to work around this limitation, by any chances?
Assume the videoLUTs are linear. I don't mind if I can only profile the
displays with the students.
All I'd like is to be able to open up an image in Photoshop and be able to
assign a newly created monitor profile. And then to be able make sense of
it, color wise, without confusing the students too much.
I'm trying to think out loud, here.
Suppose MonitorRGB for the display in Photoshop.
Why, for pedagogical sake, wouldn't I be able to load up an image with some
embedded profile, and have it converted to a freshly created ProfileMakerPro
profile, on top of the MonitorRGB profile, while retaining the expected
appearance?
Your thoughts, gentlemen, ladies, if you could. This is for a good cause.
