This photo is demonstrably "unreal." As I've said before, humans don't see out of focus light as soft, overlapping balls. And we certainly don't see the world upside down, as it is shown here in a crystal ball I inherited from my grandma Ida.
But wait a minute. . . Our eyes are lenses somewhat similar to a crystal ball. And, in fact, all that we see is upside down, too. But our brains, for some reason, turn it "right side up." So do I dare ask, "What is reality?"
