5 - 2 5. SETTINGS AND ADJUSTMENT OF CAMERA

5.2 Selecting Shutter Speed

DNS-33W has two shutter speed settings: Preset Shutter with
six different levels of shutter speed set in advance, and
Variable Shutter for which the user can set the shutter speed
to suit different shooting situations.
• Preset Shutter
Select from 6 levels of shutter speed: 1/100, 1/120,
1/250, 1/500, 1/1000 and 1/2000. Moreover, by attaching
the optional D.PROC SUB BOARD, the preset slow
shutter function by longer accumulation of CCD is added.
In this case, the preset shutter speeds are extended to 11
levels:
1s, 1/2, 1/4, 1/8, 1/15 (1/12 for PAL), 1/100, 1/120,
1/250, 1/500, 1/1000 and 1/2000.
• Variable Shutter
Set the suitable shutter speed from 1/60.5 to 1/7867
second (1/50.4 to 1/7812 second for PAL). Variable
Shutter function is effective when shooting a computer
screen that is not synchronized with the normal TV frame
rate, or a subject in quick motion such as the club swing
of a golfer in order to playback in slow motion. With a
faster shutter speed, a high-resolution picture can be shot
without blur caused by the camera shaking when shooting
subjects with vigorous movement, for example a live
coverage of a sporting event. However, the faster the
shutter speed, the larger the interval between possible
setting value becomes.
Notice
• The sensitivity decreases as the shutter speed
increases. Ensure that the lighting condition is
sufficient for faster shutter speed settings.
• As the preset slow shutter speed decreases, the
sensitivity increases, but the number of picture
frames per second decreases which causes an
intermittent freeze of a picture. Though movement
is not smooth, this is not a failure.
• When a remote controller is connected, the
operation of the remote controller has priority over
the operation switches on the camera (when SEMI
REMOTE MODE is set to "OFF").
For details on how to operate the various remote
controllers, refer to the instruction manuals
attached to the remote controllers.

pulse switch. In such a case, by pressing the SET button,
character of the shutter speed starts flashing on the VF
and the shutter speed setting is enabled. The flashing
stops automatically in approximately 3 seconds after the
setting operation ends.
