The 5D kit did not lend itself well to traipsing around San Francisco this month – or maybe I just didn&#8217;t lend myself well to carrying the load. At times I wished I had only my little Powershot, but, then, there would have been shots I couldn&#8217;t have gotten, like [...]]]></description>

<p>The 5D kit did not lend itself well to traipsing around San Francisco this month – or maybe <em>I</em> just didn&#8217;t lend <em>myself</em> well to carrying the load. At times I wished I had only my little Powershot, but, then, there would have been shots I couldn&#8217;t have gotten, like this one. I shot this just a few minutes short of Noon, against significant glare, which was compounded by shooting through an office building window.<span id="more-33"></span></p>
<p>In addition to shooting with the polarizing filter I made the following major adjustments in Lightroom:</p>
<ul>
<li>Preset: Punch (which, among other things, pushes Clarity to 50),</li>
<li>Increased Contrast and Point Curve set to Strong Contrast,</li>
<li>Increased Color Saturation, and</li>
<li>Blue channel Luminance set to zero.</li>
</ul>
<p>Beyond general improvement of the image, the primary reason for these adjustments was to bring out the blue/gray of the sky and the contrasting whites of the clouds. Of course, I could have held a polarizing filter in front of the point-and-shoot, but mine shoots only JPG, and I suspect that only in RAW could I have so easily drawn down blue luminance.</p>
