26
The
exposure control, reading light reflected
by
the
subject, measures the over-all brightness
of
the
scene it covers.
For
scenes
in
which neither high-
light
nor
shadow areas predominate, and when you
are interested equally in both, use the exposure as
determined by the exposure control.
•
Under
certain
conditions
, however, better pic-
tures are obtained by modifying the use
of
the
control.
For
example, a reading
of
a person in light
colored clothing occupying approximately half
of
the field against a very dark ba
ckground
would re-
sult in some overexposure
of
the person.
To
obtain a better picture
of
the subject, step
close to the subject and take a reading
of
the light
reflected by the subject only. Use this reading .
•
Under
certain
other
conditions
you may wish
to modify the
recommended
film speed to achieve
a result which
is
more
suitable for you. Using a
slightly higher speed results
in
slightly denser trans-
parencies, which some people prefer when using
high-wattage projectors and a small screen. A
