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.
* 50i when SYSTEM FREQ is set to 50 Hz
By pressing the AWB button, first the white
balance is adjusted automatically, then the black
balance is adjusted. Set the conditions for white
balance adjustment before proceeding.
Only the black balance is adjusted when the
WHITE BAL switch is set to PRST. •
