providing free movement (the default), horizontal, and vertical movement.
Scale Point Lets you scale the points on the graph. This moves each selected
point vertically, in proportion to its previous value. Click a point to scale, or
draw a selection rectangle around several contiguous points to select them,
and then drag any point in the selection to scale them all.
Add Point Lets you create additional points on the falloff curve. This button
is a flyout, providing linear points (the default) and Bezier points with handle.
Delete Point Removes points from the graph.
Brightening These radio buttons let you select additive or multiplicative
brightening. Additive brightening is brighter and more distinct than
multiplicative brightening. Additive brightening is useful when you use blur
in combination with a Glow effect on page 6397 . Multiplicative brightening
provides a soft highlight to the Blur effect.
Brighten Curve Lets you edit the brightening curve in the Feather Falloff
curve graph.
