See
http://home.sol.no/~gjon/depth.htm
for a bunch of links. Try out the DOF calculator.
My theory is that DOF for a given distance and aperture depends on:
W - Effective width of aperture (e.g. in mm)
E - Degree of enlargement of negative
DOF decreases as W increases and E decreases.
So ideally, you use a pinhole and reduce the negative when making the
print.
