Step Three:
The Amount slider does just what you
think it would—it controls the amount
of sharpening applied to your photo.
Here I increased the Amount to 91, and
while the photo in the main Preview
area doesn't look that much different,
the Detail panel's preview looks much
sharper (which is why it's so important to
use this zoomed in preview). The Radius
slider determines how many pixels out
from the edge the sharpening will affect,
and personally I leave this set at 1 (as
seen here), but if I really need some mega
sharpening I'll bump it up to 2.
TIP: Toggling Off the Sharpening
If you want to temporarily toggle off the
changes you've made in the Detail panel,
just click on the little switch on the far
left of the Detail panel's header.
Step Four:
One of the downsides of traditional sharp-
ening in Photoshop is that if you apply a lot
of sharpening, you'll start to get little halos
around the edge areas within your photos
(it looks like somebody traced around the
edges with a small marker), but luckily here
in Lightroom, the Detail slider acts as kind
of a halo prevention control. At its default
setting of 25, it's doing quite a bit of halo
prevention, which works well for most
photos (and is why it's the default setting),
but for images that can take a lot of
sharpening (like sweeping landscape shots,
architectural images, and images with lots
of sharply defined edges, like the one you
see here), you would raise the Detail slider
up to around 75, as shown here (which
kind of takes the protection off quite a
bit and gives you a more punchy sharp-
ening). If you raise the Detail slider to 100,
it makes your sharpening appear very much
like the Unsharp Mask filter in Photo-
shop (that's not a bad thing, but it has
no halo avoidance, so you can't apply as
much sharpening).
