The human eye, what can it see?
What is the ISO range of the eye?
What is the Fstop range of the eye?
Our eye has one shutter speed, what is it?
Just wondering...

That's all I know

should it not be the other way around? With an F22 the hot chick will all be in focus, and with a f1.4 you only have to see the face and the rest would be blurry.
The important part to note is that our eyes are constantly adjusting to what we're looking at.
Take a sunset landscape scene for example. We look at the bright sky, our eyes adjust to it and it looks nice. We then glace down to the much darker foreground. It may take a fraction of a second or longer, but our eyes adjust to it and we can see some or all of the detail.
Our brain puts the whole thing together, so what we remember is a whole scene that looks good.
A still camera, on the other hand, takes exposures one at a time...and each exposure can only have one exposure value. So if you set the exposure for the sky, the foreground will be too dark...if you expose for the foreground, the sky is too bright and gets washed out.
So when you are taking a photo, it helps to think about the dynamic range of your camera/film and know it's limitations. You might see a beautiful scene, but you should be able to recognize if it will make a beautiful photo...or at least realize that a photo won't look like how you remember it. A common thing to do, is to bracket your exposures and then pick the one you like best.
Of course, you can use grad filters or selective editing to help a photo look more like how you remember it...and now it's not hard to implement HDR techniques to blend multiple exposures.
Wow...that was longer than I meant it to be.

So most sunset pictures are "HDR"? Multiple exposes blended together?
you go girl..........<snip>And by the way, the example used in several comments is why a lot of women get turned off my junvile men.
It is my understanding, too, which brings up another question. How fast can the human eye focus?it is my understanding that the eye, and of course the brain which is involved can only focus on one plane at a time
