I'll add one (N.B. thereare better ways to do this, look up high pass sharpening to find some more detailed techniques).


Lazy high pass sharpening
  • Add a background copy layer, or a merged copy layer (if you'vegot other adjustment layers acting on the backgroundby pressing Ctrl+Alt+Shift+E, or whatever the Mac equivalent is)
  • Add a high pass filter to this layer by going through Filter > Other > High Pass
  • Adjust the radius to your liking, perhaps 5.0 pixels is a good starting point.
  • Change the blending mode of this layer to Overlay and reduce the opacity, again, to your liking. Around 50% might be a good starting point.



If you want to spend another minute, use a layer mask to confine the effect to key areas of your picture (e.g. eyes).


Here's a quick before (left) and after (right)of an eye using that method.

Another thing to remember when sharpening is just because you can make something sharper, doesn't mean you always should.
