Discussion
When the device exposure mode is AVCaptureDevice.ExposureMode.continuousAutoExposure or AVCaptureDevice.ExposureMode.locked, the bias affects both metering (exposureTargetOffset), and the actual exposure level (exposureDuration and iso). When the exposure mode is AVCaptureDevice.ExposureMode.custom, it only affects metering.
This property is key-value observable.
