Making HDR images is a difficult business. Most of the images one sees typically compress the widened range into such a narrow distribution that the result looks like a screenshot from some kind of primitively shaded first-person shooter. Even though the human visual system is able to handle bright and dark subjects much better than the average digital camera, people seem to overlook the fact that it generally doesn't do so all at once: you may be able to distinguish shadow detail in a bright scene by shifting your attention to that detail, but you aren't also having to resolve the details of bright clouds at the same time, and yet a HDR image is expected to do both and still look "natural".
