We asked you guys to send us photos. We got a photo of a woman on the beach. A giant fish statue. Teeth.

We gave them to Andreas Weigend, veteran of Xerox Parc, former chief scientist at Amazon, to see what he could deduce. A lot, it turns out.

A little Google image search, a little metadata, and we can find where you are. Maybe who you are. What color phone you’re using to take the shot, and how many SIM cards you have.

Reading photos is more than a digital parlor trick. It’s the future of commerce, marketing, policing, lending, and basically everything else.
