image and converted to the working space, the result would still
be a dark and ugly image. The source profile is as critically
important as the destination profile when making conversions,
and this illustrates that concept. You can close the Kodak 660
document, and when asked to save, click

press the

key.
Note that this linear Kodak capture is a radically different kind of image
than seen in most cases, and I used it to illustrate that indeed, an
untagged document might have pristine data but look very wrong when
that data has no profile. However, this should illustrate how any
untagged document can't be trusted! When you are given an untagged
document, all you can do is open without applying a profile by picking
the top radio button
Leave as is (don't color manage)
since this will
then allow you to use the
Assign Profile
command and pick different
profiles until you produce a color appearance that looks as good as pos-
sible. Since the document is untagged, there is no guarantee that the color
you are seeing after this profile assignment is what the original user saw.
However, you can try different profiles in an attempt to get something
reasonably pleasing.
Try picking the standard RGB working space first as it is possible
one will be close. In our example, this wasn't the case and without
having the correct profile, it would be nearly impossible to produce
good color appearance. Major image editing would be required and even
then, I doubt the image would look as good as when you assigned the
correct profile. Assigning a profile to an untagged image is simply a big
guessing game. If the untagged document comes to you in CMYK, once
again you can try assigning different CMYK profiles; however, even if
you do get reasonable color appearance, the document still might not
print correctly since CMYK images have very specific parameters for
