		<description>I'm not sure I'd call sharpening via High Pass "better" or "more powerful" than USM. It certainly is less prone to sharpening noise... but only because it's effect is generally &lt;i&gt;cruder&lt;/i&gt;&#8212;that is, it actually does an objectively &lt;i&gt;worse&lt;/i&gt; job sharpening.

Because of this, though, it certainly &lt;i&gt;can&lt;/i&gt; prove &lt;i&gt;more useful&lt;/i&gt; when you need a less aggressive sharpen.</description>

		<description>nice when used on single channels ... The weakness when using this is the blend mode that you need to use...howver masks can help a lot here too :-)</description>
