The white balance mode of the camera
typedef enum { CAMERA_WHITEBALANCEMODE_DEFAULT, CAMERA_WHITEBALANCEMODE_OFF, CAMERA_WHITEBALANCEMODE_AUTO, CAMERA_WHITEBALANCEMODE_MANUAL, CAMERA_WHITEBALANCEMODE_MANUAL_RB_GAIN, CAMERA_WHITEBALANCEMODE_NUMWHITEBALANCEMODES } camera_whitebalancemode_t;
Because not every camera supports all available white balance modes, CAMERA_WHITEBALANCEMODE_DEFAULT can be used as an alias to select a valid white balance mode.
You can use the camera_get_whitebalance_modes() function to determine which modes are supported by the current platform and camera.
