Artist's Description

In optics, a circle of confusion is an optical spot caused by a cone of light rays from a lens not coming to a perfect focus when imaging a point source. Photographers call this effect bokeh.

This abstract was created by shooting a peacock feather slightly out of focus with a very narrow DoF. I then accentuated the bokeh slightly using Photomatix.
