Black Balance Adjustments - Panasonic AG-HMC150P Operating Instructions Manual

Shooting in manual mode (continued)

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.
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.

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