```

## Discussion

This property corresponds to the [`AVCapturePhotoSettings`](/documentation/AVFoundation/AVCapturePhotoSettings) property [`isAutoDualCameraFusionEnabled`](/documentation/AVFoundation/AVCapturePhotoSettings/isAutoDualCameraFusionEnabled).

When this value is <doc://com.apple.documentation/documentation/Swift/true>, a dual-camera device automatically combines samples from both cameras to produce a higher quality image. This property applies only when using the [`builtInDualCamera`](/documentation/AVFoundation/AVCaptureDevice/DeviceType-swift.struct/builtInDualCamera) device type on supported devices.

If you specify automatic image fusion when requesting a capture, the device automatically chooses whether to use image fusion based on the scene conditions at the moment of capture. Therefore, you don’t know whether the system uses image fusion until right before the moment of capture. When the photo output calls your [`photoOutput(_:willBeginCaptureFor:)`](/documentation/AVFoundation/AVCapturePhotoCaptureDelegate/photoOutput(_:willBeginCaptureFor:)) method (or other delegate methods that occur later in the capture process), you can use this property to determine whether image fusion is active.
