(fig. 9t : ofter focusing reod the distonces in front of the
chosen operture on either side of the index [.
Exomple: in fig. 9, the focused distonce is 5m. (15 feet)
with on operture of f 22. The depth of field will thus reoch
from2.6m.(Bft 6in) to infinity, or with f 3.5, only from 4m

ihe required operture.
The obove figures ore ploced so thot,
by moving the pointer towords f13.5,
you double the volume of light to reoch

tion between operture ond speed, if you
