RANGE
OF
LIGHT MEASUREMENT
The
exposure
meter
of
the
Spotmatic
measures
the
brightness
of
the
ground
glass.
Therefore,
the
meter
should be
turned
on
after
you
have focused
your
subject
on
the
ground
glass.
The
following table shows
the
range
of
the
meter's
light measurement, and
should
not
be
interpreted
as
the
camera's total range
of
f/stop-shutter
speed combinations. As
you
will
note
from
the
table
on
the
next
page, with an
ASAlOO film,
you
may
use
any
shutter
speed from
1 sec.
to
1/1000
sec. in
combination
with any
aperture
that
will bring
the
meter
needle
to
the
midpoint
in
the
viewfinder.
The
total
range
of
the
aperture
settings is,
of
course,
determined
by
the
minimum and
maximum
apertures
of
the
lens being used.
For
example,
with
the
50mm
f/1.4
lens
and
ASA 100 film, and
aperture
from
f/l.4
(the
maximum
aperture
of
this lens)
to
f/16
(the
minimum
aperture)
may
be
used with any
shutter
speed from 1 sec.
to
1/1000
sec.
that
will bring the
meter
needle
to
midpoint.
