+## Low Light Boost
+
+For supported models (iPhone 5 and 5C), AVCaptureDevice supports a low light boost when it is detected that the capture session is in a low light area. By default, this is set to true. It can be modified with the **lowLightBoost** variable:

 When a user firsts launch SwiftyCamViewController, they will be prompted for permission for access to the cameras and microphones. By default, if a user declines access to the hardware, SwiftyCam will provide a prompt to the App privacy settings inside the iOS settings application. If you wish to change this behaviour, the **promptToAppPrivacySettings** property can be modified:
