I was sitting around today when I just started wondering how a camera auto focuses. When I ask how it focuses I mean how does the camera know that the subject is in focus? Any websites that could explain it well?

I knew, of course, that trees and plants had roots, stems, bark, branches and foliage that reached up toward the light. But I was coming to realize that the real magician was light itself.
