# isAutoDualCameraFusionEnabled

A Boolean value that specifies whether captures automatically combine data from a dual camera device.

## Declaration

```swift
var isAutoDualCameraFusionEnabled: Bool { get set }
```

## Discussion

Discussion The default setting is true, unless you are capturing a RAW photo. (By definition, RAW photos are unprocessed, and image fusion involves processing the captured image). When you enable this setting, a dual-camera device automatically combines samples from both cameras to produce a higher quality image. This property applies only when using the builtInDualCamera device type on supported devices. tip: Image processing, including dual camera fusion, increases capture time. To capture photos at the highest possible speed (like in the built-in Camera app’s burst mode), set the isAutoDualCameraFusionEnabled and isAutoStillImageStabilizationEnabled properties to false and the flashMode property to AVCaptureDevice.FlashMode.off.
