Intensity: Adjusts the strength of the sharpened edges.
Edges: Sets the threshold for which groups of pixels are edges and which ones aren’t.
Falloff: Makes the sharpening effect look more or less prominent. Increasing the falloff value makes the sharpening more severe; decreasing it softens the effect.
Tip: Position the pointer over a slider and press and hold the Option key to extend the slider’s range of values.
