3
Drag the Sharpen Amount slider to select the amount of sharpening effect from 1% to 500%.
4
Drag the Pixel Radius slider to select a radius from 0.1 to 250.
An increase in radius results in a greater area of sharp contrast surrounding each pixel edge.
5
Drag the Threshold slider to select a threshold of 0 to 255.
Values between 2 and 25 are most commonly used. An increase in threshold sharpens only those pixels of a higher
contrast in the image. A decrease in threshold includes pixels of lower contrast. A threshold of 0 sharpens all pixels
in the image.

Click OK.
