Vignetting is a lens problem that causes the corners of your photo to appear
darker than the rest of the photo. This problem is usually more pronounced
when you're using a wide-angle lens, but can also be caused by a whole host
of other lens issues. Now, a little darkness in the edges is considered a problem,
but many photographers (myself included) like to exaggerate this edge darkening
and employ it as a lighting effect in portraits, which we covered in Chapter 5.
Here's how to fix it if it happens to you:
Vignetting
Step One:
In the photo shown here, you can see
how the corner areas look darkened
and shadowed. This is the bad vignetting
that I mentioned above.
Step Two:
Scroll down to the Lens Corrections panel
in the Develop module's right side Panels
area, click on Profile at the top, then turn
on the Enable Profile Corrections checkbox,
and Lightroom will try to automatically
remove the edge vignetting, based on the
make and model of the lens you used (it
learns all this from the EXIF data embed-
ded in your image. See page 250 for more
on how it reads this data). If the image
still needs a little correction (as this one
does), you can try the Vignetting slider
under Amount.
