Feather Falloff control curve The Feather falloff curve allows you to determine the feather falloff off the Blur effect based on a graph. You can add points to the graph to create a falloff curve, and adjust the interpolation in those points. Move Lets you move the points on the graph. This button is a flyout, 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 6599. Multiplicative brightening provides a soft highlight to the Blur effect. Brighten Curve Lets you edit the brightening curve in the Feather Falloff curve graph. Blend Curve Lets you edit the blend curve in the Feather Falloff curve graph.
