5 CHANGE THE DEFAULTS
Lightroom and Camera Raw apply a
default sharpening amount of 25 to
raws (but not to JPEGs). You can tailor these
defaults, or turn them of. Click the Reset
button, input your new values, then hold
Alt and click the Set Defaults button.
6 TYPICAL VALUES
When you’re judging sharpening strength, you should usually aim to keep Amount in
the range of 80-130, with Radius between 0.8 and 1.5. Subject is a major factor in this –
landscapes and detail-rich images tend to need a higher Amount setting and a lower Radius,
while portraits typically require a lower Amount and higher Radius.
7 DON’T SHARPEN EVERYTHING
Many images
will have
detail-free or out-
of-focus parts that
don’t need to be
sharpened, as this’ll
just amplify noise.
The Masking slider
lets you conine the
sharpening to the
important parts. Hold
Alt while dragging it
to the right – areas
that appear in black
will be excluded
from sharpening.
