SHUTTER SPEEDS
This camera offers various possibilities for visual
expression by changing the shutter speed.
High shutter speeds can be used to "freeze" a
moving subject to give sharp definition of the im-
age.

speeds

can
"stop"
the
movement of a considerably fast moving subject.
A shutter speed of about 1/250 sec. will be enough
to shoot a child at play, if he is not moving too
quickly.
There are two methods for giving dynamic expres-
sions. The first one is to blur out the movement of
the subject itself, thereby creating a moving image.
The second one is to pan the camera according to
the movement of the subject. While the background
is blurred, the subject is sharply defined to create
a moving image.
* In using slow shutter speeds, it is necessary to
guard against camera shake. We will suggest a
very practical method for choosing shutter speeds.
Generally, shutter speeds of which denominator
value is larger than the focal length value of the
lens used are good for preventing camera shake.
If you are using a 50mm lens, for example, shut-
ter speeds of 1/60 sec. or higher are best; and if
you are using a 200mm lens, shutter speeds of
1/250 sec. or higher are best.
