The biggest
difJerence
between
metering
with a reflected
light
meter and
an incident
light m-e1er
is
in
step 5:
in
reflected
light metering
the
receptor
must always
be directed
at the subject
from the direction
at
which the
camera
will be
located.
There are two
major techniques
used
in reflected
light
metering:
(1)
averaging*,
in
which the entire
subject
is metered
from the camera
position,
and
(2)
spot
metering,
in
which
a narrow
acceptance
angle
is
used
to meter
a specific
part
of
the subject.
(See
Fig.
4.)
*Care
musl be
taken so that shadows
from the
meter
or
photographer
do
not cover the subject.
