Concerning the Exposure (Shutter
Speed
and Aperture Coupling)
In
order
to
obtain
the
correct
exposure, it
is necessary
to
correctly match
the
shutter
sp~ed
with
the
aperture. The
shutter
speed
and
the
aperture are
the
main factors
in
controlling the
amount
of light which
is
allowed
to
strike
the
film, and when
they
change,
the
quality of
the
image upon
the
film
also changes.
Effects
of
Changing the Shutter Speed
The
explanations below are
pertinent
to
photography with fast moving subjects
or
when it
is
intended
to
produce
impressionistic
pictures
of
movement. Depending
on
the
selection
of
the
shutter
speed,
you
can freely
control
the
expression
of
movement.
If,
as
in
example A,
the
photo
is
taken
at
a
shutter
speed
of
1/1000
sec.,
the
movement
will be frozen. If,
as
in
example '
B,
with
the
same subject,
the
photo
is
taken
at
a
shutter
speed
of
1/60
sec. with a panning
technique,
the movement
is
well expressed.
Panning is really quite a simple technique.
Hold
the
camera firmly and
continue
twisting

part
of
your
