Here is a little test, for anyone who is interested. This is how my eyes work...maybe it isn't the same for everyone else. On a fairly bright day, with some clouds in the sky, find a scene where you can see the clouds, as well as the deep shadows underneath a tree. Pine trees are ideal. In my case, I can see the bark of the tree and the dried pine needles under the tree very well, while simultaneously being able to see detail in the clouds.
Could you post a picture of this scene? I'm having difficulty imagining how I can simultaneously (without moving my eyes) see into the dark depths of a stand of trees, while simultaneously seeing clouds. The closest I can imagine is a brightly lit flower nearer to me than a stand of trees, but both along the same line-of-sight.
You move your eyes, just not a lot. The point is the scene should generally be static...you shouldn't be looking in one direction for the shadows, then turning around 180 degrees for the highlights. The point is that, while our eyeballs themselves, our retinas and the neurochemical process that resolves a "frame", may only be capable of 5-6 stops of dynamic range, our "vision", the biochemical process in our brains that gives us sight, is working with FAR more information than what our eyes at any given moment process.
Yes, that I'd believe. I think it's fair to say it's our brains that actually "see," -- our eyes just feed some raw info to the brain.
