The \l QCameraExposure -class allows you to adjust these settings. You can use this class to implement -some techniques like High Dynamic Range (HDR) photos by locking the exposure -parameters (with \l {QCamera::searchAndLock()}), or motion blur by setting slow shutter speeds -with small apertures. - -The main settings for automatic image taking are the \l {QCameraExposure::ExposureMode}{exposure mode} -and \l {QCameraExposure::FlashMode}{flash mode}. Several other settings (aperture, ISO setting, - shutter speed) are usually managed automatically but can also be overridden if desired. +camera sensor, and hence the quality of the resulting image. -You can also adjust the \l {QCameraExposure::meteringMode()} to control which parts -of the camera frame to measure exposure at. Some camera implementations also allow -you to specify a specific point that should be used for exposure metering - this is -useful if you can let the user touch or click on an interesting part of the viewfinder, -and then use this point so that the image exposure is best at that point. +The main settings for automatic image taking are the \l {QCamera::ExposureMode}{exposure mode} +and \l {QCamera::FlashMode}{flash mode}. Several other settings (aperture, ISO setting, + shutter speed) are usually managed automatically but can also be overridden if desired. Finally, you can control the flash hardware (if present) using this class. In some cases -the hardware may also double as a torch (typically when the flash is LED based, rather than -a xenon or other bulb).
