(19) EFFECT OF APERTURE AND SHUTTER SPEED Mil • High shutter speed A correct exposure is established by a combination of shutter speed and aperture setting according to the subject brightness. Actually, 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 the amount of light striking the film as the shutter stays .111 •Elt open for its designated time. If the subject is moving, its image will be blurred at a slow speed. In contrast, choosing a high shutter speed allows a frozen image to be taken of a moving subject. A high shutter speed also prevents camera shakes. It is possible to enhance the motion of a wave or a waterfall by blurring the move- ment using a slow shutter speed.

Effect

The

If
the

is
moving,
its

will

In
contrast,
choosing
a
high

speed
allows

to

A

also
