Step Five:
The next two sliders were added to
give you more control to make your
vignettes look more realistic. For ex-
ample, the Roundness setting controls
how round the vignette is. Just so you
know exactly what this does, try this: leave
the Roundness set at 0, but then drag the
Feather amount (which we'll talk about in
a moment) all the way to the left. You see
how it creates a very defined oval shape?
Of course, you wouldn't really use this look
(well, I hope not), but it does help in un-
derstanding exactly what this slider does.
Well, the Roundness setting controls how
round that oval gets (drag the slider back
and forth a couple of times and you'll
instantly get it). Okay, reset it to zero
(and stop playing with that slider). ;-)
Step Six:
The Feather slider controls the amount
of softness of the oval's edge, so dragging
this slider to the right makes the vignette
softer and more natural looking. Here
I clicked-and-dragged the Feather amount
to 57, and you can see how it softened
the edges of the hard oval you saw in the
previous step. So, in short, the farther
you drag, the softer the edges of the oval
get. The bottom slider, Highlights, helps
you to maintain highlights in the edge
areas you're darkening with your vignette.
The farther to the right you drag it, the
more the highlights are protected. The
Highlights slider is only available if your
Style is set to either Highlight Priority or
Color Priority (but you're not going to set
it to Color Priority, because it looks kind of
yucky, right?). So there ya have it—how to
add an edge vignette to focus the viewer's
attention on the center of your image by
darkening the edges all the way around.
