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 switch to the normal (OFF) shutter speed or
to slow shutter.
You switch between the progressive and normal
(60i) modes.

Press the AWB button to automatically adjust the
white balance.
Press and hold the AWB button to adjust the black
balance.

As the white balance is adjusted first when you
press the AWB button, make the necessary
preparations for this.



You cannot adjust the black balance while you
are shooting.

Auto Tracking White (ATW)

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 101)
The ATW feature is set to work in the auto mode at
the time of shipping. (Page 104)

If you use the ATW feature whenever you are
shooting, the camera automatically adjusts the
white balance as you shoot.

The ATW feature automatically determines the
current shooting environment and adjusts the
white balance accordingly. Depending on the
environment, there may be some error in the
adjustment.
Use the procedure described on the preceding
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.
