Hi Andrew, Rob,

I´d be careful though if other than "well behaved" matrix profiles are involved. If you load and save an sRGB or LStar-RGB profile in photoshop and save it under a different name, you will also have changed the tonal response curve to a gamma value. In the case of sRGB the change may be visible but tolerable, in the case of LStar-RGB, you end up with a completely different profile. I suggest to use the ColorSync utility for renaming and test extensively, if Tiger can digest these new "Generic" RGBs.

I went into Photoshop's color settings. Adobe RGB (1998) is loaded. I
clicked on "Save RGB" and saved it with the name "Generic RGB Profile icc. "
and saved it to the desktop. You can't save into the main Library folder. I
moved that profile into the Main Library (original Generic RGB Profile is
moved out). Authenticate to move the profile into place.


I think this will work to "fool the system" but you'll have to test it out
(I don't have capture).

Thanks for the further explanation. I'd misunderstood the part of the
suggestion where I'd make a *new-and-improved* Generic RGB from Adobe RGB as
you describe.
