Phase One claims 12 stops of dynamic range for their backs. For those that have a Phase back, how realistic is this claim? And specifically, how many stops above midtone can you retain details in highlights? For example, if you want to hold detail in snow, how many stops above midtone do you expose the snow for? With my Nikon D2X and D200, for example, I typically put snow or other very bright highlights at +2 or +2 1/3 stops. At +3, highlights are almost featureless white.
