ln
aperture-priority
auto, you choose
the
aperture
while
the
camera
automatically selects the shutter speed that
will produce
the optimal exposure. Large apertures
(low
f-numbers) reduce
depth
of
field, blurring
objects behind and in front
of
the main
subject.
Small
apertures (high f-numbers) increase
depth
of
field,
bringing
out
details
in the background and foreground.
Short field
depths are generally
used in portraits
to
blur back-
~
ground
details, long field depths in
landscape photographs
to
~
bring the foreground and background into focus.
Large aperture {f/5.6) Small aperture (f/16)

Choosing
an
Aperture
Rotate
the
multi
selector counterclock-
wise for
larger
apertures
(lower f-num-
bers),
clockwise
for
smaller apertures
(higher f-numbers). The
minimum
and
maximum values
depend on the
lens cur-
rently
in
use.
