title: How to trigger a bright flash like the Camera app?
body: <p>The way I am attempting to do a flash is this:</p>
  
  <p>1) Calling </p>
  
  <pre><code>[device setTorchMode:AVCaptureTorchModeOn];
  [device setFlashMode:AVCaptureFlashModeOn];
  </code></pre>
  
  <p>2) After 0.1 seconds I call </p>
  
  <pre><code>[device setTorchMode:AVCaptureTorchModeOff];
  [device setFlashMode:AVCaptureFlashModeOff];
  </code></pre>
  
  <p>Problem is, the flash is way darker than the one from Camera app when it happens. I can't get that LED to shine as bright. Is there a different way to let this flash as bright as possible?</p>
