If you've ever used a camera, you know how any error in lighting, focus or motion can ruin a photo. Turning light into even the worst of the above images requires incredible technology.
Eyes are pretty useless unless they are complete and perfected.
If you're viewing this page with a standard 800x600 resolution monitor, you're seeing 480,000 of pixels of light. A 56KB modem delivers web content at 5,600 bytes of information per second. In comparison, your eye sees about 125,000,000 pixels of light through five distinct kinds of neurons, processing about ten, million-point images per second. Your eye is remarkably efficient, able to produce a signal with only one photon. Copyright Evolution of Truth, 1997-2001.
