If you want to get an idea
of how many shots—
especially in TV spots—
have vignetting, it's very
hard to see if you look at
the center of the screen,
but focus your eyes on the
corners and you will see
this on more shots than
you would expect.

on the kiss and the softness is expanded. The yellow lines are optional UI
overlays that let you know the boundaries and shape of the vignette.
You can see that this can be a very effective way of enhancing a shot
( Figure 5.39 ) .

Geographical Color Fix

You can also use spot color correction to solve a problem that exists in just
a specific area of the picture, or to enhance just a specific area of the pic-
ture. For our example, call up the “ultralight_horizon” clip ( Figure 5.40 ) .
This is not the best way to select the grass and/or sky, but it will work
for the purpose of the tutorial. The best way to do this correction “in real
life” is to use the same method that we used earlier in the chapter when
explaining the Final Cut Pro Limit Effect using the same clip. Let's con-
tinue with this method, though, so that you see how two different meth-
ods can be used to the same end result.
