Uses of the Variable Shutter Control Ring — Adjusting
Exposure
When shooting people against the light, the subject will be under-exposed.
In such situations, move the exposure adjustment scale to "2" or "4" for
proper exposure.
When shooting a theater stage under strong spotlights, the darkness around
it may cause the picture to be over-exposed. In such situations, reduce the
shutter angle so that proper exposure can be obtained and blur be avoided
at the same time.
• The numbers "2” and "4" on the scale of the variable shutter control
ring adjust exposure to 1/2 and 1/4 respectively.
• Exposure can also be adjusted by means of manual aperture control.

As shown in the chart, if the shutter angle varies, the shutter speed changes
even when filming speed remains unaltered. When shooting moving subjects
such as sports, blur can be prevented by reducing the shutter angle. Thus,
each frame will be sharply expxssed.
