277/365 Holiday bokeh

"Bokeh" is one of those ambiguous terms that refers to one general photographic technique -- but no one can seem to agree on one absolute definition.

Some say it's simply the technique used in creating a very blurred background, usually featuring spots of light of some kind -- like the lights on the Christmas tree above.

Others say it's the more creative technique of turning those light spots into shapes.

What's the one, true definition? Who knows? I like the effect, whatever it means and whatever you want to call it.

Camera: Canon 40D with 60mm macro lens and 430EX Speedlite, 1/125s, f/2.8 at ISO 100
