I recently read this message posted to Mac Fix It page. It concerns me a
little. Here is the message and then I will express my concern.

From Macfixit today:
Photoshop Color Settings bug Jon Kane discovered a Photoshop Color Settings
bug, that has been confirmed by Adobe Tech Support. He writes: "If you
change your color setting to anything other than the default setting (web),
the new color settings are not applied to an existing image with a different
color space. An example would be when you change your color settings from
SWOP Coated to SWOP uncoated, the image on your screen should darken
slightly to show the difference in dot gain. This way you can correct the
image if necessary. Now if you open an existing image that is not in the
current color space (or grayscale image), any change to the color space (or
grayscale dot gain) will not show on screen for correcting. Adobe Tech said
that this bug should be fixed in a future update."

Is this in fact a bug? I would think not myself. As I see it, what is
happening, in the process of changing color space in the color settings
dialogue box, if you expected the image to change this would mean you are
expecting the image to take on the new profile without a conversion taking
place. I thought this type of profile treatment was being avoided with
Photoshop6 and the assign profile function was the only place where profiles
could be manipulated and possibly mismatched.
Isn't this the exact behavior that Photoshop 5 had that 6 was supposed to
fix?
When the working space profile changes in the color settings box, the reason
the image does not change is because (if you look at the assign profile
after making this change) the profile that was previously assigned as the
working space profile is now assigned to the image itself. I think this
makes more sense.
I can see how it might make things easier if you have 5 or more images open
and all have the working space profile assigned and by changing the working
space profile, it will change the working space for all these images. But I
also see the need to preserve the embedded profile and allow profile
reassignment only through the assign profile menu.
As for the part about opening existing images that are not "in the current
color space" (I assume he means working space) Of course the image is not
going to show a change if you change the working space, because the images
profile is assigned to the image and not the working space profile.
What are the opinions on this? Is it correct for Adobe to consider this a
BUG? Or is this a feature that simply protects the integrity of the images
profile. Who is overlooking what here?
Maybe I am overlooking or misunderstanding the problem here. If not I would
be very concerned if they did change this behavior.
