edit: I wanted to add, it really amazes me, the human eye can adjust fast enough, that when you scan over the surroundings you can see the detail. HDR makes it possible to see the image a lot closer to the way I see it.
From (-2EV, 0EV (standard), +2EV)
You can see where the detail is pulled from each of the pictures. Not a lot from -2EV. In fact, a lot of the pictures, I do not include it. Especially if there is a lot of wind, I will just use 0EV and +2EV.
