Amount The amount determines what percentage of change will occur. The default setting is 50 percent. Increase up to 100; decrease down to 1. A higher percentage makes the effect stronger.
Radius The radius determines the depth of pixels that are affected at the edge you’re changing. The default setting is 25 pixels. Increase up to 100; decrease down to 0.1. A larger radius causes more of the pixels surrounding the edge pixels to be sharpened.
Threshold Threshold determines the level of brightness to be used for differentiation. The default setting is 0 levels. Increase up to 25. A lower value produces a more pronounced effect.
