Adjusting the White Balance and Black Balance
To record high-quality video with the AG-3DP1, the black
and white balances must be adjusted according to
conditions.
For higher quality, it is recommended that the adjustments
should be made in this order AWB (white balance
adjustment)
ABB (black balance adjustment)
AWB
(white balance adjustment).
NOTE
If white balance and black balance adjustments are made
while the video image is distorted due to GENLOCK, the
adjustments may not be correct. Wait for the video image
to return to normal before performing white balance and
black balance adjustments again.
