Unsharp Mask
Using Unsharp Mask, the user can increase the sharpness of photographs by making edges
more dis tinct. Unsharp Mask works by increasing the contrast of the edges in the image while
leaving other areas untouched. The amount of sharpness is determined by three factors: in-
ten si ty, halo width, and threshold.
