Off-topic, but Iliah has done a great job at debunking the HDR myth. Even if you have a
sensor that's sufficiently linear over that range, optical systems are a real limit.
Much past a dozen stops, even if you're merging multiple images, and you're just doing
more and more to capture the nuances of your lens flares and the camera's mirror box's
internal reflections. And scenes with that much dynamic range are typically
uncomfortably bright and rarely pleasant to look at. Who actually stares into the Sun
when watching sunsets?
John McCann's book "The Art and Science of HDR Imaging" goes to great lengths
to illustrate the glare issue in optical capture systems. The human eye is as
limited, if not more in this respect, than any artificial image capture system.
