Step Two:
When the High Pass filter dialog appears,
drag the Radius slider all the way to the
left, so that everything turns solid gray.
Now, drag the slider to the right until
you can just start to see the color peek
through the solid gray (as shown here)—
the farther you drag, the more intense
the effect will be (here, as an example,
I dragged to 7 pixels, and you can see
lots of edge detail starting to appear).
When you're done, click OK.
Step Three:
To bring the shar pening into the image,
go to the top of the Layers panel and
change the duplicate layer's blend mode
from Normal to one of these three modes:
(1) for medium sharpening, choose Soft
Light; (2) for heavy sharpening, choose
Overlay; or (3) for just insane sharpening,
choose Hard Light (as shown here). If the
sharpening seems like it's too much, you
can lower the opacity of this duplicate
layer. Think of this as the control for the
amount of sharpening, so try lowering the
Opacity amount (at the top of the Layers
panel) to 75% (for 75% of the sharpening),
or 50% if that's still too much. So, that's
High Pass sharpening, but there's another
option, and in the next step, we'll look at
limiting where the sharpening is applied
(and keeping some of the glow around
the edges in check).
