Chapter 4 Adjustments and Settings for Recording — Adjusting the white and black balance

Adjusting the white and black balance

To obtain high-quality video at all times using the camera, the white and black balance must be adjusted according to conditions.

To obtain higher quality, perform the adjustment in the order of AWB (white balance adjustment) → ABB (black balance adjustment) → AWB (white balance adjustment).
