When making ref
lected-
light
readings,
the meter
measu
res
and averages
the
light
ref lecting
f rom
all subjects
within
its
field
of view. Like
all
reflected-light
meters,
the Auto Meter
lV F
is
calibrated to
provide
an
exposure which will
reproduce
the metered
area as a tone
with 18% reflectance
(zone
5)
regardless
of
its
true
shade.
With
practice,
you
should
be able
to
pre-visualize
how
you
want various
parts
of
your
scene to
appear
in
the
final image.
You will
then
be able to take
a
reflected meter reading
of any
area and, by adjusting
the data
provided
by
the Auto Meter lV
F,
obtain
a correct exposure.*
Reflected readings,
together
with the meter's
brightness-
difference f
unction,
enables
you
to
quickly
and
easily deter-
mine
the
brightness
range
of a scene
(see
p.41).
With this
information,you
can then
adjust the exposure
and/or
pro-
cessing
to fit
your
film's
exposure
range. Reflected-light
readings
are
also useful when
you
want
to
meter
subjects
which
emit
instead
of
reflect
light.

To make a
ref
lected-light
reading,
attach
the
ref lected-light
attachment,
Viewfinder

or
Viewfinder

"
ll to the
meter.
Position
the
receptor
head so
that
it is reading
the
area
you
want
to
meter
without
casting
a shadow
on
this area or being
affected
by surrounding
parts
of
the scene
or other
lights.
*
lf,
for example,
you
meter an
area
which
is
one
stop
brighter
than
zone 5,
you
will
have to
increase the
metered
value
by
one
stop
in
order
to
make
this area appear
with its original
brightness.
lf
you
meter
an
area
which
is
one stop
darker
than
zone 5,
you
will
have
to decrease
the exposure one
stop
to
keep
it from appearing
brighter
than
normal.
Here
again,
with
practice
you
will be able
to
recognize the
relative
brightness
of
various shades
regardless
of their color.
