The word bokeh originated from the japanese word "boke"(pronounced bo-keh) meaning blurred or fuzzy.
When shooting especially portraitures, photographers like to use shallow depth-of-fields to only focus on the subject while blurring out everything else. We call the blurred part "bokeh"
Bokeh can be achieved primarily by using a big aperture.

Hmm..if you post it here, you might not get sufficient replies. I've noticed that this particular thread is quite inactive.
Try this, look for your camera brand's thread and try posting there.

Heh. Even if you cant find the specific thread for your camera, you could always drop by any of the brand's thread. The "pros" would be more than happy to show off their "skills" ;P

Well, them photographers have large egos....So I captioned the word "pro" ;D
