Adjusting The White Balance (In Custom Mode) - Sony SRW-9000 Operation Manual

Adjusting the White
Balance (in Custom
Mode)
When adjusting the white balance, select a white
balance memory bank. The filter is fixed to CC:A
(3200K) when the preset memory is selected.
You can check the selected memory bank with the
status display on the viewfinder screen (see page
62), and select it on the subdisplay or from a
connected remote control unit.
Note
When using the unit in Custom mode, readjust the white
balance if the lighting conditions change.
To adjust the white balance
automatically
1
Select memory A or B, using the
subdisplay or the RM-B750 Remote
Control Unit (default: preset memory).
For details on how to select on the subdisplay,
see "Selecting Gain, Color Temperature, and
White Balance Values" (page 47).
2
Adjust by turning the filter selector
knobs.
3
Place a white pattern in the same
lighting conditions as the subject and
zoom in on it to obtain a white area in
the screen.
A white object (white cloth, a white wall,
etc.) near the subject may be used in place of
a white pattern.
The minimum white area required for
adjustment is as illustrated below:
A rectangle centered in the screen.
The length of the sides must be at
least 70% of the height and width of
the screen.
Within this rectangle, there must be
an area of white greater than 10%
of the entire screen.
Note
Be careful not to have any high luminance spots in
the rectangle.

Adjust the lens iris opening or set the
shutter to ON.
With a manually adjusted lens: Set the
opening to an appropriate value.
With a lens that has automatic iris control:
Set the lens automatic/manual iris
control switch to automatic.
Or, set the video level to an appropriate
value, using the shutter setting.
5
Perform automatic white balance
adjustment.
The message "AWB: EXECUTING"
appears on the viewfinder screen. If the
adjustment process succeeds, the message
"AWB: OK" appears.
If automatic white balance adjustment fails
If the automatic white balance adjustment process
fails, the error message "AWB: NG" appears on
the viewfinder screen for about three seconds.
If this error message appears, try adjusting the
white balance again.
If the subject has a higher color temperature, use
an optical filter or set 5600K to ON, then try
white balance adjustment again.
If the error message continues to appear after
several attempts, the unit requires internal
inspection.
Note
When you execute the automatic white balance
adjustment function on a system where the Select FPS
function (see page 106) is enabled, set the FPS value
(number of frames to shoot) to a value greater than
