That's the way I thought it was supposed to work, but it doesn't seem to be the 
case with my current settings.  If I don't convert to the monitor profile, 
images look right to me in Digikam but look wrong on other computers (or in 
non-color-managed programs on this computer).  If I do convert to the monitor 
profile, the image's appearance doesn't change in Digikam, but it looks right 
everywhere else.  And it doesn't matter if I strip the profile out of the file, 
either.

What seems to be happening is that I'm seeing the image through my monitor's 
profile, and adjusting it to look right with that profile applied.  But anywhere 
that doesn't use the monitor profile looks wrong, because it's not getting the 
effect of the monitor profile.

Oh, something that might be important: although I have color management turned 
on, when I try to convert to a color profile in Digikam it informs me that "this 
image is not color managed".  I'm not sure why it's not, though.  I've looked at 
every setting related to color management and can't see what else I would 
change.  I've actually been using another color-managed program (Gimp) to do the 
conversion, since Digikam wouldn't let me.  If this is the problem, then how do 
I get Digikam to treat images as color managed?  (These images are starting as 
RAW files in Digikam, and most are not being processed by other programs, so I'm 
not sure why it won't color manage them.)
