It’s an age-old trope: the enhance in the movie that can zoom into a finitely granular photo in order to see the face of a killer in someone’s eye. It’s a beautiful McGuffin, a way to stick in a little tech nerdery into an otherwise boring scene.
It also saves writers from having to think up really good scenes.
