setting within the range previously set with the setup

This switch activates the white balance and black balance
automatic adjustment functions.

GAIN selector
This selector switches the gain of the video amplifier to
match the lighting conditions during shooting. The gains
corresponding to the L, M, and H settings can be selected
from the setup menu. The factory settings are L = 0 dB, M
= 9 dB, and H = 18 dB.
When this selector is adjusted, the new setting appears on
the setting change/adjustment progress message display
area of the viewfinder screen for about 3 seconds.
For details about setting the gain values, see “5-3-1
Setting Gain Values for the GAIN Selector Positions” on

OUTPUT/DCC (output signal/dynamic contrast
control) selector
This selector switches the video signal that is output to the
VTR, viewfinder, and video monitor, between the
following two.
BARS: Outputs the color bar signal.
CAM: Outputs the video signal from the camera. When
this is selected, you can switch DCC
1)
on and off with
this selector.
1) DCC (Dynamic Contrast Control)
Against a very bright background with the iris opening adjusted to the
subject, objects in the background will be lost in the glare. The DCC
function will suppress the high intensity and restore much of the lost detail
and is particularly effective in the following cases.
•Shooting people in the shade on a sunny day
•Shooting a subject indoors, against a background through a window
•Any high contrast scene

t
WHITE BAL (white balance memory) switch
This switch controls the white balance setting.
PRST (preset): Adjusts the color temperature
corresponding to the position of the FILTER selector.
Use the PRST setting when you have no time to adjust
the white balance.
A or B: When the AUTO W/B BAL switch is pushed to
WHT, the white balance is automatically adjusted
according to the current position of the FILTER
selector, and the adjusted value is stored in either
memory A or memory B. (There are two memories for
each filter, allowing a total of eight adjustments to be
stored.) When this switch is set to A or B, the
camcorder automatically adjusts itself to the stored
value corresponding to the current settings of this
switch and the FILTER selector.
You can use the AUTO W/B BAL switch even when
ATW

is in use.

The white balance of the picture being shot is adjusted automatically for
varying lighting conditions.
