"The mental processing required to perceive images is so great that it represents about 40% of the body's at-rest caloric consumption. This is why it's so resting to close our eyes for a moment. (I forget the citation for the 40% number, let me know if you have it exactly.)"

Eyes resolution: 1/60th of a degree (Google converging lines test pattern)
Eyes effective shutter speed: 1/30th of a second. (video is like 1/48th of a second)
I agree with Ken's complaints about the state of HDR images, they've become ubiquitous since Adobe added an automation feature in PhotoShop, but they still have weird artifacts. What we need is a camera sensor that is able to adjust the gain on a pixel level, mapped ISO, or a high resolution LCD screen that could act as a masked ND filter. Heck i should patent that! They make those sun-glasses that have light sensitive darkness to them, they should put a really thin on over the sensor of a D-Camera
This is great example of decent HDR, where the images is appealing and doesn't have the weird highlights of an auto HDR job. Here is another great one, where it still looks somewhat realistic. And one more from wikipedia
