adjust edge definition in the image. Camera Raw provides four adjustments
to help you fine-tune image sharpness.</p>
<p>Use the Apply Sharpening

is applied to all images or just to previews.</p>
<div class="tip"><img src="images/tip_help.png" />To
open preferences from within Camera Raw, click the Open Preferences

the toolbar. To open Camera Raw preferences from within Adobe&#160;Bridge,
choose Edit&#160;&gt; Camera Raw Preferences (Windows) or Bridge&#160;&gt;
Camera Raw Preferences (Mac&#160;OS). To open Camera Raw preferences

<li class="stepexpand"><span>In the Detail tab, adjust any of these controls:</span> <dl><dt class="dlterm">Amount</dt>
<dd>Adjusts
edge definition. Increase the Amount value to increase sharpening.
A value of zero (0) turns off sharpening. In general, set Amount
to a lower value for cleaner images. The adjustment is a variation
of Unsharp Mask, which locates pixels that differ from surrounding
pixels based on the threshold you specify and increases the pixels’
contrast by the amount you specify. When opening a camera raw image
file, the Camera Raw plug-in calculates the threshold to use based
on camera model, ISO, and exposure compensation. </dd><p class="dlseparator"></p><dt class="dlterm">Radius</dt>
<dd>Adjusts the size of the details that sharpening is applied
to. Photos with very fine details may need a lower setting. Photos
with larger details may be able to use a larger radius. Using too
large a radius generally results in unnatural-looking results.</dd><p class="dlseparator"></p><dt class="dlterm">Detail</dt>
<dd>Adjusts how much high-frequency information is sharpened
in the image and how much the sharpening process emphasizes edges.
Lower settings primarily sharpen edges to remove blurring. Higher
values are useful for making the textures in the image more pronounced.</dd><p class="dlseparator"></p><dt class="dlterm">Masking</dt>
<dd>Controls an edge mask. With a setting of zero (0), everything
in the image receives the same amount of sharpening. With a setting
of 100, sharpening is mostly restricted to those areas near the
strongest edges. Press Alt (Windows) or Option (Mac&#160;OS)
while dragging this slider to see the areas to be sharpened (white)
versus the areas masked out (black).</dd><p class="dlseparator"></p></dl>
