Digital BW, The Print

Martin, I hope someone who lists Bokeh as one of their Gods will put up
a really good example of the same image, one taken with a lens with
"bad" bokeh, and one with a lens that has simply Supergobslopsius bokeh.
 I want to see the actual difference.

In any case, I can't see a landscape photographer having any interest in
an out of focus area, as there usually aren't any.

I can just picture Ansel Adams, Just before taking his Moonrise over
Hernandez picture yelling at his assistant: I can't take this picture,
The lens on my camera doesn't have good bokeh!
