The Edge of the Known World

I'm responding to a challenge issued by blipper Markus Hediger: Low Depth of Field/Tip or Rim of Anything. The idea is to use a wide aperture and focus on the edge of an object, throwing the rest of the image into soft focus. The succulents gave me lots of colors to play with, and definitely some nice edges. You can find all the entries by clicking on EP14 in my keywords. Thanks to Markus for always keeping it interesting!
