Hyperfocal Distance Photography: Calculations & Focus
"the special focus condition called Hyperfocal Distance (HFD) and
how you can employ it with today’s DSLR cameras to achieve the absolute
greatest possible depth of field for any given situation. Hyperfocal
focus will allow you to produce a DOF that extends from the nearest
possible point to the camera through to infinity."
"Now here is the key point: HFD is calculated using only three numbers,
the lens focal length, the f-stop used and the circle of confusion."

"To round out your understanding of HFD, proceed to dofmaster.com
and download their free HFD calculator. Input of all values required on
the data screen is pretty straightforward except the circle of
confusion which you should initially set at.019mm for most handheld
digital cameras. If you want to more know about circle of confusion, you
can read further on their website. In any event, program the screen and
output your HFD chart."
