This picture was taken with a camera 70,000 x 30,000 pixels (2100 MegaPixels). It can identify a face in a multitude. The cameras are not sold to the public and are being installed in strategic locations. (This one is in Canada).
Place your cursor anywhere in the multitude of people and left double click a couple times. Wait a moment and It will continue to show the people much closer, when you double left click again or click more if needed. Amazing !
One can get more flexible viewing by using the +/- cursor and the full screen view icon below the +/- control for an even clearer view of a face. Cannot count the freckles, but darn near. There were thousands of people and yet they can spot and recognize any face. Imagine what this means…
