# automaticallyEnablesExposureSignals

When true (the default), capture sessions may automatically modify `enabledExposureSignals` based on changes to other device or session properties.

```
var automaticallyEnablesExposureSignals: Bool { get set }
```

## Discussion

The `enabledExposureSignals` property can only be assigned when `automaticallyEnablesExposureSignals` is false, otherwise assignments to `enabledExposureSignals` will throw an exception.

> Throws: `NSGenericException` if assigned without first obtaining exclusive access to the receiver using ``doc://com.apple.avfoundation/documentation/AVFoundation/AVCaptureDevice/lockForConfiguration()``.
