(16) EFFECT OF APERTURE AND 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 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.
