The HDR pro app needs two pictures to align, taking each at a different exposure. However ghosts of people are created when individuals walk into view while the camera was still taking the preliminary photos. Those shown here are all immersed in cell phone activities and seem present yet very much apart from one another. I think that when you are with another person, or even walking in the street, if you are immersed in your personal iPhone or other smart device, you avoid all the interactions that make us the social animal we are. You become a ghost, an invisible non-being, a person non-persona.
