title: Capture dual pictures with iPhone 7Plus and AVCaptureSession
body: <p>I am working on this piece of swift 3 code:</p>
  
  <pre><code>captureSession.sessionPreset = AVCaptureSessionPresetPhoto
  
  let videoCaptureDevice = AVCaptureDevice.defaultDevice(withDeviceType: AVCaptureDeviceType.builtInWideAngleCamera,mediaType: AVMediaTypeVideo,                        position: .back)
  
  let videoInput = try AVCaptureDeviceInput(device: videoCaptureDevice)
  
  if captureSession.canAddInput(videoInput)
  {
      captureSession.addInput(videoInput)
  }
  </code></pre>
  
  <p>Then, i take a picture with an AVCapturePhotoOutput object and i get the picture in AVCapturePhotoCaptureDelegate object.</p>
  
  <p>It works fine.
  What i want to do is to take a picture with the iPhone 7 Plus dual camera. I want to get 2 pictures, like the official iOS camera app:
  - One picture with background blur
  - A second picture, without blur</p>
  
  <p>Do you think it is possible ?</p>
  
  <p>Thanks</p>
