I saw this pic in Flickr’s ‘interesting past 7’. First, I love it. Second, it shows that the fancy bokeh and shallow DoF are not always the way to go. Third, how the hell did he get such wide DoF? Is it from the small Powershot sensor? Is that why Elsinore uses one for her bug Pr0n?
That’s going to have a lot to do with it, in addition to the small sensor. There’s some pretty hardcore calculus equations that go into determining it, but this page breaks it down into plain words pretty well. It also features a DoF calculator to do all the hard work for you.
