Let
f be the lens focal length,
N be the lens
f -number, and
c be the circle of confusion for a given
image format. The
H hyperfocal distance is approximately given by:
\(\large H\approx\frac{f^2}{Nc}\)

The basis of these formulas is given in the section Derivation of the DOF formulae; [10] refer to the diagram in that section for illustration of the quantities discussed below.
Hyperfocal distance[edit]
