DIMINISHING OR ADDING VIGNETTING
Vignetting can be caused by a
mismatched filter/lens hood or a lens
(e.g., using a filter on an ultra wide
angle lens). It can also be caused
by using wide angle lenses not
optimized for digital capture (i.e., not
optimized for even brightness across
the frame).
To add or diminish a vignette:
Select the Lens Corrections tab 1.
by clicking on the icon circled in
Figure 9-42.
Adjust the Amount slider left 2.
or right. The edges will darken
or lighten from a central radial
point. In the case of Figure 9-43,
photographer Luis Delgado
Qualtrough actually darkened the
edges of his image to bring more
attention to his subject. (The
image, by the way, was taken in
Copenhagen with the Canon 5D
and is part of his ongoing series,
“Regarding the Hero and Anti-
hero”.)
Use the Midpoint slider to expand 3.
or decrease the range of the
effect. You cannot, however,
create multiple interest points.
Adding a vignetting effect is
therefore most effective when
your image contains a single
point of interest that you want to
emphasize.
