Thanks, Piers.  You caused me to go back and reread Mike's last message. 
 I have to agree now that he means binary when he says digital after 
reading: "My reference to digital/analogue was referring not to 
technology but to the way of thinking. Hyperfocal is a digital concept. 
Inside the arbitrarily marked zone is ON, outside is OFF. Look through 
the viewfinder and turn the focusing ring and what you see is analogue."
But I think what he doesn't understand is that the marked zone is 
definitely not arbitrary.  It's arbitrary from his standpoint since he 
wants to use his image for something other than a deliberately composed 
and focused landscape.  But the hyperfocal method is designed exactly 
for deliberately composed and focused landscapes.  If you want to make 
an arbitrary crop of some arbitrary piece of the image you're doing a 
different type of photography.  Don't demean hyperfocal methods if they 
don't pertain to your method of photography.  I use it when it suits the 
image I want to produce but not when it's inappropriate.
