Oh, so many problems here!
- Pictures taken using the camera are not saving at full resolution.
a) If “captureToFile” is true, then “media.capturePhoto” writes the image to disk, then we add that image to the iPhone photos, but the image is NOT full resolution.
B) If “captureToFile” is false, we save the display objects created by media.capturePhoto…and the image is NOT full resolution.
- The camera feed works wonderfully…until I tap the “Take Picture” and launch the native camera interface. Once that happens, the feed stops. If I suspend the app (tap the home button), then start it again, the camera does refresh.
Please help!

I wish to take full-resolution photos.

I really wish I could trigger a full-resolution camera photo directly from Corona (not by tapping in the native interface).
