You used to be able to get lost in the crowd, but not anymore.
This is a photograph of 2009 Obama Inauguration. You can see IN FOCUS the face of EACH individual in the crowd !!!
You can scan and zoom to any section of the crowd. . . Wait a few seconds. Double click anywhere. And the focus adjusts to give you a very identifiable close up.
The picture was taken with a robotic1474 megapixel camera (295 times the standard 5 megapixel camera). Every one attending could be scanned after the event, should something have gone wrong during it.
