Depth
of
Field
When
focusing
on a
certain subject,
there is
an area
both
in front
and
behind
the subject
that can
be held in
focus.
This
range is
called
the.depth
of field.
When
the range
is wide
it is
a deep
defth
of field
and
when
the^range
is narrow
it
is a shallow
depth of
field. Depth
of
field
has
the followins
characteristics

requires
the
use of infrared

lncorrect
exposure
may result
when you
snap
the
shutter in
taking
pictures
against
backlight
or extreme
difl'erences
in
brightnesi
between
the
main
subject
and the
background.
At
those
times,
compensate
for
exposure.
There
are two methods
of
exposure
compensation
(see
Figs.
30
and 3l).
1)
Using
the
exposure
compensation
dial
(Fig.

In
both focus priority

and manual

the standard

set
for
exposure
compensation
are shown
in

for
depth

can be
read
by the

that
are
on every

are the

The
depth
of field graduations
are
written
in relation-io

can
generally
be read from
