Thread
the
film and
run
off
the
leader
as
described on pages
11
to
16.
If
the
frame
counter
dial does
not
read 0 or very close
to
0, remove the
film chamber from
the
mechanism.
Push
in the
PLUNGER,
Figure 51,
page 54, push the EXPOSURE BUTTON
until
the dial reads very close
to
0,
then
operate
the
SINGLE
FRAME
RELEASE
until
the
0 index
line is
exactly
at
the
pointer. Set
the
CAMERA
FILM
METER
so
that
the
figure
SO
or
0
(SO
for SO-foot rolls; 0 for 100- or 2oa-foot
rolls)
is
exactly
at
the
index line.
Then
replace
the
film chamber.
After these adjustments have been made, the
two
dials give a range
of
4000 frames before
they
start
repeating.
The
FRAME
COUNTER
will
be found very useful.
For
example,
suppose
you
wish
to
start
a double exposure
when
the
CAMERA
FILM
METER
reads between 7 and 8 feet and the frame
counter
reads
23.
The
total
reading is 7 feet
23
frames, or
it
can be expressed
as
303
frames.
At
the end
of
the first exposure
take
another
reading, for example 12
feet 16 frames (496 frames)' A
length
of 193 frames has been run, or 4
feet
33
frames. Close
the
shutter
and
wind
the
film
backward
to the
7-foot 23-frame
position;
open the
shutter
and
run
to
the 12-foot 16-
frame
position
again. Stopping
at
the exact frame for
the
second time
requires some practice.
If
there
is
motion
in
the
scene,
it
will
be neces-
sary
to
watch
the
rotating
dials and
stop
as
close
as
possible to
the
desired position.
But
if
there is no
motion,
it
is possible
to
stop
a
little
short
of
the desired reading, set
the
shutter
at
U
-OPEN
to compensate
for the increased exposure, and proceed to the end
of
the
scene by using
the
SINGLE
FRAME
RELEASE, see page 49.
For
double exposures there is
another
way
to
return
to the exact
starting
position
when
rewinding. Before
starting
the
first exposure,
wind
the spring tight by
turning
the
MOTOR
CRANK
in
the
direction
of
the
arrow.
Wind
slowly
after
the
bell rings because
the
mechanical
stop
will
act
after three turns
of
the
MOTOR
CRANK. After
the
first
exposure, close
the
shutter
and
wind
the
film
backward
with
the
hand
crank
on
the
EIGHT-FRAME
SHAFT,
until
the mechanical
stop
pre-
vents
further
turning
of
the
hand
crank.
That
the
film is
now
at
the
exact
starting
position
can be
noted
by checking
the
reading of the
two
dials.
