(16) EFFECT OF APERTURE AND SHUTTER SPEED 85 High shutter speed A correct exposure is established by a combination of shutter speed and aperture setting according to the subject brightness. There are many correct combinations of shutter speed and aperture for a particular subject brightness. Different shutter speed and aperture settings produce different effects. Effect of Shutter Speed The shutter speed determines the film exposure time, or a.. the length of time that light is allowed to strike the film. If the subject is moving the image will be blurred when a slow shutter speed is used. It is possible to enhance the effect of motion, (The movement of a wave or wa- terfall) by intentionally using a slower speed. Choosing a high shutter speed will allow the image of a moving subject to be frozen. A higher shutter speed also helps prevent camera shake. SNOLLVEI3dO CI3ONVACIV III Slow shutter speed

AND
SHUTTER
SPEED
a..
High

Slow

85
A
correct
exposure
is
established
by
a
combination
of
shutter
speed
and
aperture
setting
according
to
the
subject
brightness.
There
are
many
correct
combina-
tions
of
shutter
speed
and
aperture
for
a
particular
sub-
ject
brightness.
Different
shutter
speed
and
aperture
settings
produce
different
effects.
Effect
of
Shutter
Speed
The
shutter
speed
determines
the
film
exposure
time,
or
the
length
of
time
that
light
is
allowed
to
strike
the
film.
If
the
subject
is
moving
the
image
will
be
blurred
when
a
slow
shutter
speed
is
used.
It
is
possible
to
enhance
the
effect
of
motion,
(The
movement
of
a
wave
or
wa-
terfall)
by
intentionally
using
a
slower
speed.
Choosing
a
high
shutter
speed
will
allow
the
image
of
a
moving
subject
to
be
frozen.
A
higher
shutter
speed
also
helps
prevent
camera
shake.
