So vision is not effortless. Nor is it faithful: if you ever believed that your brain gives an accurate representation of what is “out there” in the same way that a movie camera would, then David Brown’s untouched photographs should quickly disabuse you of that notion. Instead, your attentional machinery slowly crawls the scene, analyzing interesting landmarks until it detects what is useful for the next step. In the case of one of Brown’s visual moments in time, you might be in the middle of looking for the door to the shop, or where to step, or whether the traffic light is ready to let you cross. All the other details are unconsciously and nimbly filtered out. – Dr. David Eagleman
