Effectiveness of the Variable Shutter Control
The variable shutter control increases the effectiveness of shooting,
besides the exposure adjustment, since a fast exposure time may
be attained at the same filming speed.
1 Since a shutter speed of 1/158 sec. can be obtained, even with a
• 18 fps setting, it prevents a moving subject from appearing blur­
red as well as blurring caused by moving the camera.
O High filming speed may be used to film a moving subject at slow
^ speed and to get a sharp picture.
Q When the incoming light is exceeded, the exposure volume can be
” adjusted by two steps.
Fadings and Rewinding by Variable Shutter
Since the variable shutter control lever adjusts shutter from fully
open to totally closed, fade-ins and fade-outs can be easily under­
taken. Moreover, overlappings can also be performed by utilizing the
rewinding mechanism.
Fade-Out
By sliding upwards and shifting the variable shutter control lever
towards the "CLOSE” position, the shutter can be closed and the
picture gradually darkens and finally fades out.
■ By sliding the lever to "S” the film advance will be interrupted
and will prevent wasting of film.
Fade-In
By shooting the film while progressively returning the variable shut­
ter control lever from the "CLOSE” position to the "OPEN” side,
the dark picture gradually becomes brighter.
■ The fading technique is used in movies when there is a change of
scene. Generally speaking, the fade-ins are used at the beginning
of a movie and the fade-outs at the end. The fading technique
may also be used to show the elapse of time or a sudden change
in scene, although it should not be used too frequently.
■ For a quickly changing scene, a fading of l-1.5sec. would be ade­
quate, or about 2-3 sec. in the case of a slow moving scene.
