If you look at the two elevations, (Left "Elev" = 3757 or there about, that is the Ground Elevation and the Right "Eye Alt = 3793 or there about, is where you have placed the virtual camera.) they differ by about 36 feet... I am pretty sure you can see faces and shirts from 40 feet... But neither of thoses is the altitude of the camera. Did anyone ever explain Zoom or Telephoto lenses? You know some of the images in Google Earth were taken from satellites hundreds of miles above the earth... and you can see cars and swimming pools and everything except the Great wall of China.

I believe this picture was actually taken from less than 500 feet above the ground.
