Adjusting the white balance and black balance
Adjusting the white balance
Preset white balance
Set the WHITE BAL switch to PRST. The white
balance for the selected filter is now obtained in
accordance with the position where the FILTER
control (outer) has been set.
If the preset white balance is to be left unchanged for
use, skip ahead to "Adjusting the black balance" (page
56).
White balance adjustments using the
AWB function
A better picture can be achieved by adjusting the
white balance and black balance in the following
sequence: AWB (white balance adjustment) 5 ABB
(black balance adjustment) 5 AWB.
There is usually no need to re-adjust the black
balance even when the power has been turned off
and back on.
The white balance must always be re-adjusted when
the lighting conditions have changed.
If the display mode is set to "2" or "3," messages
advising the user of what progress has been made in
the adjustments and what the adjustment results are
appear on the viewfinder screen when the black
balance or white balance adjustment is commenced.
Set the display mode to "1" if these messages are not
to be displayed.
O For details on the display mode settings, refer to
"Display modes and setting change messages"
(page 48).
<Notes>
O ABB must be performed when the MASTER GAIN
levels have been changed on the LOW SETTING,
MID SETTING and HIGH SETTING screens of the
FILM (CAM) MAIN MENU 1, when the super gain
setting has been changed using the USER button,
and when the GAMMA (ON/OFF) has been
switched on the CAMERA SETTING screen.
O With artificial lighting—particularly fluorescent lights
and mercury lamps—the luminance may appear to
be constant but the intensity of the R, G and B
colors will change in synchronization with the power
line frequency. Especially in regions with a 50 Hz
power line frequency, mutual interference arises
between the vertical sync frequency (approx. 60
Hz) of this unit and lighting frequency (50 Hz). As a
result, the hue tends to change with the passage of
time or flickering occurs, making it impossible to
achieve a proper white balance.
It is recommended that the white balance be
achieved using the settings shown in the table
below.

refer to the description of the FILTER control
