Detailed Description
CameraFlash is part of the QtMultimedia 5.0 module.
This type allows you to operate the camera flash hardware and control the flash mode used. Not all cameras have flash hardware (and in some cases it is shared with the torch hardware).
It should not be constructed separately, instead the flash property of a Camera should be used.
import QtQuick 2.0 import QtMultimedia 5.0 Camera { id: camera exposure.exposureCompensation: -1.0 flash.mode: Camera.FlashRedEyeReduction }
