2. Employing
Cine Scale
lncident and
ref
lected light
measurements during
cine
pho-
tography are
performed
in
the
same
manner as described
pre-
viously.
However,
since
the cine
scale
@
numerals
correspond
to
cine camera
film
speed,
read the
aperture
scale
@
indication that
pertains
to the
employed
film
speed.
Note: Some cine cameras
possess
faster exposure times due
to
a
narrower rotating
shutter angle
(angle
of
light
transmitting
portion).
lt is
important
to
know the accurate
film
speed
versus shutter angle
value
for
your
camera
in order to
determine
proper
exposure. Refer
to
the camera
operating
instructions, maker's catalogue,
etc.
for
shutter
speed
inf
ormation.
