Black balance adjustments
In order to reproduce the black accurately, adjust
the zero level of all three RGB primary colors. If the
black balance is not adjusted properly, not only will
the black be reproduced poorly but the color tones
of the entire screen will also be downgraded.
It is not normally necessary to adjust the black
balance. Adjust it when:
• You use the camera for the first time.
• You use the camera after not using it for a long
time.
• The ambient temperature changes greatly.
• You change the gain and shutter speed.
• You switch to the CAM mode from the PB mode.
• You change the SYSTEM FREQ.
• When you change the shutter speed to 1/8 or
less
White balance can be adjusted automatically by
pressing the AWB button, while black balance can
be adjusted by holding the button down. Set the
conditions for white balance adjustment before
proceeding.

• Black balance can be adjusted by holding
the AWB button down even when the ATW
function is in use.
• You cannot adjust the black balance while you
are shooting.
• Black balance adjustment takes around 30
seconds when the shutter speed is 1/8 or less.
• If “ABB NG” message appears, attach the
lens cover, then try adjusting the ABB again.
Auto Tracking White (ATW)
Using the ATW function enables the recording
environment to be automatically analyzed and an
optimum white balance to be constantly maintained
during recording.
You can allocate the ATW feature to one of the
positions on the WHITE BAL switch (A, B, or
PRST). Allocate it by going to the setup menus,
SW MODE screen, ATW. (Page 54 of Vol.2)
White balance sensor
• Depending on the environment, there may be
some error in the adjustment.
• Use the procedure described on the previous
page whenever you need more precise white
balance.
• Do not block the white balance sensor when
using the ATW feature. ATW will not work if
you do.
