Digital BW, The Print

For those poor souls like myself going "Bokeh?" here are a couple of sites:

http://www.kenrockwell.com/tech/bokeh.htm
http://www.pathcom.com/~vhchan/bokeh.html
http://www.pathcom.com/~vhchan/bokeh.html
http://www.trenholm.org/hmmerk/ATVB.pdf

You can find many more with a web search. Obviously a hot topic. I am more
of the f:90 LF school so I have not really paid any attention to this. My
initial reaction is that it seems much ado about very little, but I will
reserve judgment as it has not been an issue in my work.
