I am not sure if this is possible with Corona but I have seen this on other apps on the iPhone.

Essentially what I need to do is display some guides on screen at the same time as the camera is being used in an app. So for example I was taking a photo of a face, I would have an oval guide that the user must attempt to adjust the phone position until their face fits within the oval.

So my question is basically, can I launch the camera within my app and have a graphic overlap the camera viewer screen?

Thanks
