Setting The Electronic Shutter; Shutter Modes; Selecting The Shutter Mode And Shutter Speed - Sony PDW-510 Operation Manual

5-3 Setting the
Electronic Shutter
This section describes the shutter modes that can be used
with the electronic shutter of the camcorder, and describes
the procedure for selecting the shutter speed and shutter
mode.

5-3-1 Shutter Modes

The shutter modes that can be used with the electronic
shutter and the shutter speeds that can be selected are listed
below.

Notes
• Whatever the operating mode of the electronic shutter,
the sensitivity of the CCD decreases with increasing
shutter speed.
• When the automatic iris is used, the iris opens wider as
the shutter speed increases, thus reducing the depth of
field.
Application
• Under artificial light, particularly fluorescent or mercury
lamps, the light intensity may appear to be constant, but

such lighting could make the flicker even worse. Color
flicker is particularly likely to happen when the power
supply frequency is 60 Hz (with the PDW-510/530) or
50 Hz (with the PDW-510P/530P). However, if the

Hz (with the PDW-510P/530P), setting the shutter speed
to 1/100 or 1/60 can reduce this flicker.
• When a bright object is shot in EVS mode or ECS mode
in such a manner that it fills the screen, the upper edge of
the picture may have poor quality because of an inherent
characteristic of CCDs. Before using EVS mode or ECS
mode, check the shooting conditions.
You can turn on or off the EVS mode on the SW STATUS
page of the PAINT menu.
