Step Three:
Now, what if it doesn't instantly come
up with a profile (or the camera data is
missing from the file) when you turn on
Geometric Distortion? In that case, you
can sometimes help it along by choosing
your camera's make, model, and even
lens from the pop-up menus in the Search
Criteria section. In this case, they didn't
actually have my camera model listed in
the Camera Model pop-up menu, and
even when I chose the lens I did use, here,
the Auto Correction doesn't look right.
This is why this works best if it can match
it to a profile in its database automatically,
rather than having you choose it here.
However, sometimes this works great.
If you don't see the exact lens model,
I usually try the next closet profile, and
that will often do the trick.
Step Four:
If, after choosing your camera make
and model, no profiles show up in the
Lens Profiles listing box, try clicking the
Search Online button (as shown here).
It will go to Adobe's own servers, and
check to see if any additional profiles for
your camera make and model have been
added by end users (as long as you're
connected to the Internet, of course). If
it does find some, they'll be listed there,
and all you have to do is click on one to
apply it. In this case, it didn't find any
additional profiles for my lens, so it re-
verted back to the original profile it first
provided (which actually looks pretty
good). Although it did a pretty good job
of fixing the barrel distortion (the bow-
ing out of the columns), there's still kind
of a perspective problem (look at how the
columns are leaning out to the left and
right—smaller at the bottom and leaning
outward as you get to the top).
