Pentax digital spotmeter User Manual

CINE INDEX
The operation
of the
spotmeter
for
movie
cameras
differs somewhat from
that of
still
photography.
The
shutter speed of movie
cameras is
determined
by camera
type, the shutter
opening angle,
and
whether the
camera is being used for
high or
low speed
photography.
The standard
shutter speed of the
ordinary 35
and
16mm movie
camera
is approximately 1/50
of
a
second
(24
frames
per
second). This
speed
is
marked
in red
on the
Shutter Soeed Scale between
the 1/30 and 1
/60
sec. divisions. Theref
ore, when
using the meter
with these cameras,
the aperture
opening
is
found
on
the Aperture
Scale below
this
mark.
With
Bmm
movie
cameras,
the
Super-B
and Single-B
types take 1B frames
per
second,
and the Double-B
type takes
'l
6
f
rames
per
second. In
both cases,
the
proper
aperture opening
will be found
on
the
Aperture
Scale below
the 1/30 sec. mark.
