Satoshi T I thought "bokeh" is outfocus ,and "blurr" is shaking or movement by slow shutter. It is just bokeh I think.
vera Hahaha! I think we had better to read the blog of Pawel on the weekly theme... "Bokeh is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light".=)
vera I think that a bokeh is a blurred background... but I'm not sure and not specialist. Perhaps someone could be able to give us a better light on that, not so blurred as mine :-)))
