Well, I'm not rushing on P6. And I don't think CL should be rushing. As for this HDRI stuff. 1 bit works out the same as 1 stop for a photographer. 8-bit grey-scale is around two stops better than you can get on a photographic print, and maybe even a bit better than the negative. Most lenses can be adjusted over a 7-stop or 8-stop range at most. But real life can be a bit wider-ranging. And a lot of the art and science of photography is about getting the important bits of real life looking right, without carelessly throwing away the extremes.
