Re the Camera app on my Android 4.2.2 tablet :
When I aim the rear-pointing camera at a subject and place two fingers on the screen I see an overlay image of two concentric circles (one 5” in diameter and the other 1” in diameter) with a single line connecting the circumference of the smaller circle to the circumference of the larger circle.
Can someone please tell me the function of that image? Why (and how) do I use it? Thanks. ..... batpark
