Finally I like to apply an unsharp mask. With all of the previous steps sometimes a little sharpness is lost. I use a preset of amount 85, radius 1, and threshold 4.
Over sharpening can produce a halo effect around the edges. This Unsharp Mask works by increasing the contrast along the edges in an image. My above preset values produce a subtle degree of sharpness without any haloing. Again I click OK to make the correction.
