By “where in the world,” I don’t mean the country, or even the city. I mean, the precise GPS co-ordinates of where your iPhone or iPad was when the photograph was snapped.
The information is stored inside a photo as Exif data, alongside all sorts of other details collected about the picture you have taken—including the make and model of your camera, its shutter speed, whether you used a flash, and the date and time.
