Subject: [Leica] HYPOfocal distance
From: brad daly <bwdaly@bigfatpipe.net>

okay, i understand how hyperfocal distance works--in fact, i used it 
today while walking around scaring the bezeesus out of people on the 
streets of chicago by unexpectedly taking their pictures--but what about 
hypofocal (???)[1] distance?  for instance, say i stop my lens down all 
the way, then focus it all the way to the *closest* focusing distance.  
i know i have some depth of field *closer* than the plane of focus, but 
i don't know how much.

is there a formula for calculating this?

[1] i'm totally aware that "hypofocal distance" is probably something i 
just made up.  if so, i get the neologism of the day award.  and for 
once, a new word and/or phrase i created isn't dirty.  momma's gonna be 
so proud.

always been to be an American, the ridiculous mix of the grand and 
pathetic, the painfully self-aware and the mockworthy clueless spiritual 
state that has gotten us so far ahead and so sadly behind the rest of 
the world.
