adds a mask that targets the contours of an image, allowing more aggressive sharpening
with fewer side effects. Like Edge sharpening
, High Pass sharpening
(named for the filter used to produce the effect) targets contours in an image, but it does so without the need for a mask. Unlike Edge sharpening
, the contour accentuation it produces is soft, feathered and wide. The effect is substantially different and can be used for many creative effects. High Pass sharpening
is very similar to the effects of ACR and Lightroom's Clarity slider, but it offers more control and more varied effects.
