One-Push:
Used in conditions where AWB (Auto White balance) is unable to detect and use a white image to auto set the white balance.
- Fill the frame with what you know to be a white object (even under colored lighting). This is saved as the camera's "white" reference.
- The camera now auto-white-balances using the new reference "white" instead of it's internal reference.
