Formulas
According to Eric Renner at least 50 charts suggesting optimal pinhole
diameters have been devised in the last 125 years (Renner 1995:118). In my
own reading the last six years I have come across about fifteen charts or
formulas, a few of which may be derived from the same basic formulas. It
should be noted that the diameter of the pinhole is not really critical. But for
every focal length there is an "optimal" diameter, i.e. a diameter which
produces the sharpest possible image. The word optimal actually is not a
felicitous term, since the pinhole photographer or artist may not be striving
for the greatest possible sharpness. There are beautiful pinhole images
which are intentionally softer than what is technically possible. A good
pinhole image is something else than a blurred, out of focus, lens image.
