.
lf
you
are
in
ambient
mode
and cannot
hold the meter
steady
so that the spot
circle
remains
over
the
area
you
are
measuring,
the
brightness-difference reading may
change.
Set the
meter
to
cord
mode. Now
when
you press
the
measuring
button,
the meter
will not make
continuous
measurements. You
must
still
hold
the measuring
button
down after the second reading
to
view
the
brightness
difference
in +/-EV,
but the reading will not
change if
you
move
the spot circle to
an area of different brightness.

USING
THE
ANALOG
SCALE
The Auto
Meter
lV F's analog
scale can
help
you pre-visualize
the
placement
of
midtones, shadows
and
highlights
from
your
scene
in
the
final image.
Based on
your
own
past
experience
and
knowledge
of
the exposure
latitude
of
your
film,
this
will
help
you
to
judge
whether
the exposure
provided
by the
meter
will reproduce
the scene as
you
desire.
Attach
Viewfinder 5
"
or
Viewfinder
10' ll
(5'
is
preferable)
to
the
Auto Meter
lV
F
and
make a
reading of
:
.
the brightest
area
in which
you
want
to
retain
detail
if
you
are
using
reversal
film;
.
the
darkest
area
in which
you
want to retain detail
if
you
are
using
negative
film. Store
this
reading in memory.
Next,
measure the darkest
(reversal
film)/lightest
(negative
film)
area
which
you
want to show detail and
place
this
reading
into memory
also.
lf necessary, adjust
the shutter
speed
to
bring
both
readings
onto
the analog
scale.
This
is the brightness
range
of
your
scene--highlight
read-
ing
on
the right, shadow
on
the
left.
