15. How to Choose a Shutter Speed
The shutter controls exposure by the length of
time it remains open.
The basic function
of shutter speed is to get
correct exposure, but you can
also use it to con-
trol the expression of your subject's motion and
to control the effect of camera movement.
Blurring part of the picture can heighten the
sense
of action. In most cases, however, image
blur is undesirable. To avoid blurred pictures
from camera movement. use a shutter speed of
at least 1/ 60 second for handheld shooting with
a standard
(50 mm) lens. Even higher speeds are
necessary with a telephoto lens. See pp. 45-46 .
I wonder what 150 / ASA film
speed is.
Oh , I forgot to tell you. I asked our
film dealer about that. He told me
that the higher the film's 150 /
ASA speed , the less the light it
needs for exposure.

That
with a higher film
speed we can shoot in
lower light or use
faster shutter speeds.
Good
work!
