Example of use:
If you were using a 24mm lens and select f/11 as your aperture, the Hyperfocal Distance would
be 2.5 meters or 8.4 feet. If you focus at that hyperfocal distance
, the depth of field
in your image
would be from half of that distance (1.25 meters or 4.2 feet) to infinity
Since modern lenses don't have DOF engraved marks in their barrels anymore, you need to
estimate where in your scene is that hyperfocal distance read from the table to focus on.
As long as it is approximate you'll be fine.
