 Inside: The default setting. When set to Inside, all adjustments you make affect the
interior of the secondary matte (the area in white, when looking at the mask itself ).
 Outside: When set to Outside, all adjustments you make in that tab affect the
exterior of the secondary matte (the area in black). Making a darkening adjustment
to the outside of a softly feathered circle matte that surrounds the entire frame is
one way of creating a traditional vignette effect.
 Copy Inside to Outside: Copies the correction that’s currently applied to the inside of
the matte to the outside as well. This is a handy operation if you want to copy the
same correction to the outside as a prelude to making a small change, so that the
difference between the corrections applied to the inside and the outside is not so
large.
 Copy Outside to Inside: Copies the correction that’s applied to the outside to the
inside.
 Swap: Switches the corrections that are applied to the inside and outside of the
secondary matte, so that they’re reversed.
Using the Secondary Curves
The secondary curves are a deceptively powerful set of controls that allow you to make
specific adjustments to the hue, saturation, and luminance of an image based solely on
regions of hue that you specify using control points on a curve.
