We've seen what the three policies do and that when the Embed-
ded Profile Mismatch appears, we have the option to pick any of the
three radio buttons depending on what we want to do, although I can't
see why anyone would use the off policy to strip away profiles. The
reason we have this control is that we have asked Photoshop to always
present a warning dialog, thus allowing us to make up our minds case
by case. However, there is a way to automate the process, which adds
control and danger depending on your outlook.

1. Open the Color Settings and set the policy for RGB documents to
Preserve Embedded Profiles . Now turn off the Profile
Mismatches: (Ask When Opening) check box and click OK .

2. Open Dog_in_Bowl.tif . It opens with NO warning whatsoever
in sRGB. 2 This is exactly the same behavior we saw earlier,
where the original color space was kept intact (preserved) with
the big difference being we got no Embedded Profile
Mismatch warning dialog.

3. Close the Dog_in_Bowl.tif document. Then open the Color
Settings , change the policy to Convert To Working RGB , and
click OK .

4. Open the Dog_in_Bowl.tif document once again. If you look at
the Document Profile indicator, you will see the data was
converted to Adobe RGB (1998). This happened with no
warning dialog because the warning check box was off. As you
can see, this speeds up the process in situations where a user
might want to automatically convert any document not in their
preferred working space to the preferred working space. In some
cases, this can be dangerous as you might have converted data
you didn't really want to convert! If you configure the policy to
Off , then any document opened will have its embedded profile
stripped out with no warning. This is even more dangerous than
setting the policy to Off and having the Warning check box on.

What you should be able to see from the tutorial is that the various poli-
cies play a far lesser role, if any, when the warning check boxes are on.

Note that the very first time a user attempts to open a document when turning
off this warning check box, Photoshop will still show a modified Embedded
Profile Mismatch warning with a Don't show again check box. This is a
one-time safety net provided by Adobe to ensure that you really do want the
warning turned off. If you see this warning, go ahead and click the Don't show
again check box to continue with this tutorial. There are a number of such
one-time warnings and once set, they can be returned to the original condi-
tion by going into the Photoshop Preferences/General settings and clicking
the Reset All Warning Dialog button.
