This isn't how it works in Panther's Preview or Mail applications.
I'd be interested to know if people are getting the same on-screen
colours, *on tagged images* in Photoshop and Mail/Preview/Safari/ and
other 3rd party software.
Mail and Preview respect embedded profiles and use them as source for
both RGB and CMYK, in both Jaguar and Safari. Safari sort of does in
Jaguar but I forget in what way it does not, and don't have any 10.2
machines here to test. But in 10.3 Safari respects embedded profiles in
RGB JPEG whether dropped on the icon, or called by HTML. For TIFF it
will respect embedded profiles when the image is dropped on the Safari
icon; not sure if it does if called by HTML.
iPhoto 2 ignores embedded profiles when an image is initially added;
but upon subsequent launching of the application it will respect
embedded profiles.
Keynote's behavior is a little wonky. It respects embedded RGB and CMYK
profiles, but it does not really do display compensation because it's
not using the display profile as the destination. Rather, it uses
Generic RGB as the destination. Generic RGB is also used as the assumed
source for untagged RGB images. Yet if you Save as PDF, untagged RGB
images are tagged with the current display profile; CMYK images are
converted to RGB and also tagged with the current display profile. The
most unfortunate fall out is the lack of display compensation which
means any custom profiles for a projector are not used.
In Microsoft Word and Powerpoint it's a total disaster. An embedded
profile affects the display of both TIFF and PDF, but are displayed
differently. Both are wrong. And how they display also depends on the
RGB Default profile selected in ColorSync preferences AT THE TIME THE
FILE IS PLACED INTO THE DOCUMENT. Embedded profiles in JPEG are
ignored, monitor RGB is source and destination. No accurate display
compensation occurs. (Since these apps were written for 10.1, and a
number of things have changed under the hood since then, and I'm using
them on 10.3.1, who knows if this has anything to do with it.)
I mentioned this about a year ago, when I started having
inconsistencies (around the 10.2.4 update?). Basically, I have 2 apps
which show the same colours Live Picture and Photoshop... the others
are inconsistent (but all the same). All I've deduced so far is that
there's a bug... just don't know what it is. *:) Seems like some apps
may either apply profiles twice and sometimes apply the wrong one.
Over saturated, then under-saturated.
The state of affairs with the non-Adobe applications in terms of color
management is far from good, let alone far from perfect.
