A better likeness would be if she was smiling, but it&#8217;s a lot to ask of someone to hold a frozen smile for 20 minutes while they&#8217;re being drawn.

			<content:encoded><![CDATA[<p>High Dynamic Range, or HDR, photography has become quite popular in recent years, and for good reason; check out these <a href="http://www.2expertsdesign.com/2009/06/02/85-examples-of-beautiful-hdr-photography/" onclick="pageTracker._trackPageview('/outgoing/www.2expertsdesign.com/2009/06/02/85-examples-of-beautiful-hdr-photography/?referer=');">gorgeously wonderfully stunningly inspiring examples</a>.</p>
<p>If you don&#8217;t have an HDR monitor to display a true HDR image, you can create a 32-bit-per-channel HDR image in Photoshop from two or more identical photos taken at varying exposures (File &gt; Automate &gt; Merge to HDR).</p>
<p>However, if you&#8217;re like me and don&#8217;t own a tripod, then you can also fake the HDR effect in Photoshop using a single image; I stumbled across <a href="http://www.nill.cz/index.php?set=tu1" onclick="pageTracker._trackPageview('/outgoing/www.nill.cz/index.php?set=tu1&amp;referer=');">this online tutorial</a>, and the results inspired me to try it for myself. I didn&#8217;t follow the tutorial exactly, experimenting with different layer opacities and layer blending parameters. The key step in this approach is based on Photoshop&#8217;s Shadow/Highlight command, which allows the user to lighten underexposed regions and  similarly darken overexposed regions. It does this based on the surrounding pixels (local neighborhood) in the shadows or highlights.</p>
<p>Here&#8217;s my result. &#8216;Cute Bear&#8217; becomes &#8216;Cute HDR Bear&#8217;:</p>
<p><img class="alignleft size-large wp-image-165" title="fake-hdr-compare" src="http://donnadupuis.ca/wp-content/uploads/2009/11/fake-hdr-compare-689x1024.jpg" alt="fake-hdr-compare" width="489" height="725" /></p>
<p>Kay, so it&#8217;s a far cry from real HDR, and HDR from merging multiple images, but it&#8217;s still a pretty cool effect. Photoshop love!</p>
