Hi, we have HP Omni 10.0 with Windows 8. With native camera app can take 8MP photo.
We need take photo with own software. We use sample application (http://code.msdn.microsoft.com/windowsapps/Media-Capture-Sample-adf87622 )
We can capture photo 3264x1836 resolution with native camera app, need to do this in our app.
In sample we added some code.
imageProperties->Width = 3264;
imageProperties->Height = 1836;
But our app can't capture high quality photo and can't change photo's scale.
