Oh, I overlooked the code sample you provided. You should listen to the imageAvailable() signal instead of imageCaptured(). What you get from imageCaptured() is just a preview, it's emitted right after the camera sensor captured the image but at this point the final image is not processed yet. That final image is provided by imageAvailable(). You'll notice it's a QVideoFrame and you'll have to convert it to a QImage if that's what you need.

I just used the basic example in the docs to capture an image like this: camera->searchAndLock(); //on half pressed shutter button imageCapture->capture(); //on shutter button pressed camera->unlock(); //on shutter button released and had setup the viewfinder and camera like this: camera = new QCamera; viewFinder = new QCameraViewfinder(picture1); viewFinder->setSizePolicy(QSizePolicy::Maximum,QSizePolicy::Maximum); viewFinder->setGeometry(picture1->geometry()); imageCapture = new QCameraImageCapture(camera); connect(imageCapture, SIGNAL(imageCaptured(int, const QImage &)), this, SLOT(gotImage(int, const QImage &))); camera->setViewfinder(viewFinder); imageCapture->setCaptureDestination(QCameraImageCapture::CaptureToBuffer); camera->setCaptureMode(QCamera::CaptureStillImage); Everything works as expected. The problem is with the exposure settings. The viewfinder looks how I want it to (properly exposed). But when I capture the image, it is under-exposed (very dark). I was hoping to get the picture that is taken to have the same exposure settings as the viewfinder since it looks fine. Does anyone know why the default settings for QCamera would be under-exposed in comparison to the viewfinder? Thanks!
