Controlling the brightness
How to set/operate
1. Set the AUTO/MANUAL switch to MANUAL.
2. Press the SHUTTER SPEED button to highlight the shutter
speed setting.
3. Adjust the shutter speed using the SEL/PUSH EXEC dial.
Note: A shutter speed of 1/100 sec is displayed as 100. Thus a
higher value indicates a faster shutter speed.
The shutter speed can also be used to control the quantity of
transmitted light.
In still photography, both the shutter speed and the aperture
(iris) are used to control the light volume. With video cameras,
however, shutter speed is more problematic. Faster shutter
speeds can cause subject movements to appear brittle and
unnatural, while slower shutter speeds can make movements
and camera panning appear jerky.
