<p>Recently I met Alexander Black, a professional photographer who has dived deeply into the world of super macro photography. Super macro is the ability to focus to 0 distance from the lens. That&#8217;s right &#8212; it can focus on an object in direct contact with the lens (when I went to the pro camera shop looking for a camera with super macro, they insisted such a thing did not exist).</p>
<p>Super macro opens up some interesting possibilities; if you look at Alexander&#8217;s <a title="Alexander Black's Website" href="http://alexanderblackphotography.com" target="_blank">website</a>, you&#8217;ll see what I mean &#8212; the photos look like abstract art, and combine beautiful forms and color.</p>
<p>Initially we were looking at buying the Canon Powershot SX10, and were tempted (ok I was, Sandra didn&#8217;t care) by the addition of 1080p video on the Powershot SX1, but unfortunately neither of these were in stock at our local store. They had an Olympus SP-590, but the Olympus was considerably more expensive than the SX10 and did not have HD video like the SX1, so&#8230;</p>
<p>I looked on eBay, and scored a Canon Powershot S2 for around $100, the cheapest solution by far. I figured Sandra and I would have a chance to play with this feature, and if we liked it spend the extra money &#8212; or perhaps would discover the 5mp &#8220;old tech&#8221; was just good enough. Sandra has been playing with this camera all day.</p>
<p>The above photo was my first serious attempt at using this camera, judge the results for yourself. When I get a chance to build a serious gallery, I will. Oh, and other than reducing the size, the above photo has not been altered in any way in Photoshop (no color adjustments at all).</p>

<p>Sandra and I packed up our cameras and favorite lenses and headed to <a title="Anza Borrego State Park" href="http://www.parks.ca.gov/?page_id=638" target="_blank">Anza Borrego State Park</a>, an immense desert wilderness. There we joined a group of student photographers that combined learning about the natural history of the area with learning about how to take better pictures.</p>
<p>Take a look at my <a title="gallery here" href="http://paulkeet.com/galleries/anzan_borrego/index.html" target="_blank">gallery here</a>!</p>
<p>Here are the most important things I learned about photography while there:</p>
<ul>
<li>Lighting is the most important ingredient for any photo.</li>
<li>Always shoot on manual exposure, otherwise you don&#8217;t control the lighting.</li>
<li>The lighting level should be set to maximize the details of the subject of your photo, too dark and too light areas outside of that are less important.</li>
<li>Every photo should tell a story, this is the basis of composition.</li>
<li>Make your exposure a little darker to get blue skies, also shoot away from the sun.</li>
<li>Get up early!</li>
<li>Control depth-of-field, which often means carrying a tripod&#8230;</li>
</ul>
<p>Digital SLR&#8217;s have much larger sensors than their point-and-shoot counterparts, which give them much smaller depth-of-field for a given aperture size (f-stop). Sometimes this is desirable, you can put the focus directly on your subject and blur the foreground and background, like this photo <a title="here" href="http://paulkeet.com/galleries/anzan_borrego/content/anza_borrego_022_large.html" target="_blank">here</a>. But this is not always desirable, when you are taking a landscape photo you often want the entire shot in focus &#8212; you need a very large depth-of-field.</p>
<p>To get a very large depth-of-field you need to use a small aperture (a large f-stop) like f16 or f22, which also means there is less light falling on the sensor, so the exposure needs to be longer. And a longer exposure will only work if you take it on a tripod, you just can&#8217;t handhold a 1/4 second exposure even if you have image stabilization. So you need a tripod.</p>
<p>This is also true for macro photography, I have the wonderful Canon 180mm f3.5 Macro lens, but taking a photograph of a nearby small object at f3.5 will result in a razor-thin depth-of-field: if you are shooting a photo of a bee, only part of its head will be in focus, and the rest blurred. So, again, you need a very stable platform for your camera &#8212; a tripod. Unfortunately that won&#8217;t stop the bee from moving, so for insects I do bump the ISO up as much as I can even in bright light so I can narrow the aperture (increase the f-stop) and maintain shutter speed.</p>
<p>So: serious photographers use manual exposure, and own a good tripod.</p>
