- We are unable to see individual still frames faster than about 30 fps. Which is why "video" looks like "video" to us... the frames merge in our minds.
- ISO is a measure of sensitivity. The f-number of the human eye varies from about f8.3 in a very brightly lit place to about f2.1 in the dark. At 1/30s ("human frame rate") i would guesstimate the best ISO of the eye to be around ISO800-3200.
- 100 gigapixel? Actually, iirc, the human eye resolution is very very low. It works differently from a camera, and can only make out details at the point where it is concentrated on, the rest of the scene is a blur of colours.
- The "built-in stabilizer" would be the brain, not the body. In fact, our beating hearts and jittering muscles are probably the reason why we need those mechanical stabilizers in the first place.
- The eye actually has weaker focusing than camera lenses. A camera lens can focus on one plane at a time (DOF is actually another term for "acceptable blur"); so can the eye, but the brain can only extract information from one tiny area at a time.
Thanks for the info...learn something new. By the way, need not be so serious on jokes...
