Dear Bill,

That is correct. You're experiencing that the monior profile is used
from Photoshop [1]. When your display is calibrated and has an
accurate profile, this will result in the "right colors" shown to you.
The Apple color picker will show you the RGB values which are sent to
the display, while the Photoshop color picker will show you the RGB values
which are in the file. Both values will differ normally, because
Photoshop uses the monitor profile to adjust the RGB values which are
sent to the screen. There would be only one case when both values
would be the same: if your monitor would have the same color space
(speek profile), like your file. In a non-pro setup you might have
sRGB choosen for your display and you could work in sRGB space on a
sRGB file from you digital camera.
So the Photoshop colorpicker shows you the values of the file, while
the systemwide colorpicker shows you which RGB values are used to
display a specific pixel in this way that the "meaning" of the files
pixel value is preserved.
[1] Photoshop does this together with the system colormanagement
(ColorSync on a Mac or ICM on a PC).
