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 
(50i) modes.

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

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 88)
The ATW feature is set to work in the auto mode at 
the time of shipping. (Page 90)

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.
