Why - when compared, say, to a camera sensor - does the human eye have such a high dynamic range

if you have a damaged pixel itll show up. Your eyes and brain cheat. I think I read somewhere once that the eyes also capture images much faster than the brain can process them.That said Im not a photographer so Im not entirely sure as to what issues youre referring too.......
Take a photo of a sunset with great variation in the amount of light in different parts of the photo, and you'll have to Photoshop it to fix problems.

Look at the same sunset with your eyes, and you have no trouble at all.

Why?

-
Because your brain comes with some pretty impressive image editing/analysis software of its own. That's the reason why optical illusions work - your brain can't interpret them properly.

An example being of how you can only focus on quite a small area at once - you just don't notice because your eyes are almost always skipping around. It also edits out boring stuff such as blinking. If you pay attention you'll notice then, now did you notice for the minute before reading this? You blink 3-30 times per minute and I'll bet you didn't.

Ultimately a camera faithfully reproduces what it sees, if you have a damaged pixel it'll show up. Your eyes and brain cheat. I think I read somewhere once that the eyes also capture images much faster than the brain can process them.

That said I'm not a photographer so I'm not entirely sure as to what issues you're referring too.
