Blackmagic Design Pocket Cinema Camera Manuel D'installation Et D'utilisation page 211

NOTE Customizing the white balance or tint will change your preset to 'CWB,' or
custom white balance. Custom white balances are persistent; your CWB settings will
stay configured between power cycles, and when switching to a preset and back to
CWB. This makes it easy to compare a custom white balance to the last preset used.
Auto White Balance
Your Blackmagic Pocket Cinema Camera can set white balance automatically. Tapping 'AWB'
will bring up the white balance screen.
When setting white balance automatically, a square will be overlaid on the center of your image.
Fill this square with a neutral surface such as a white or gray card and tap 'update WB'. The
camera will automatically adjust its white balance and tint values so the average of the white or
grey inside the white balance square is as neutral as possible. Once updated, this will be set as
your camera's custom white balance. Holding the WB button on the top of your camera for three
seconds also selects automatic white balance and activates the 'update WB' function.
Tapping the 'AWB' icon in the white balance menu will bring up the auto white balance screen.
Use this with a white or neutral grey surface to automatically set a neutral white balance
