May I suggest that you visit the Phase.com website and view Joe Cornish's images with the 45+ and IQ180. Tell me truthfully if those images have thesame image charactistices of 4x5 images. THere are simply too many issues with DOF (check out the distant subjects),color accuracy and of course it is not always desirable to obtain 12 stops of dynamic range detail. I have always been impressed by Joe's images of the seacoast using traditional film; whereas, his IQ images dont' seem to render the same impact. The holy grail (at least for color) of greater DR is simply overstated. These images have plenty of resolution but the dynamic range reduces contrast and, in my opinion, makes the image quality seem frail, thin and without power. It's almost as if the resolution and DR overtakes the photographer's statement about the character of the light. I would question the color accuracy of many of the images as well. Having spent years looking at dynamic outdoor lighting, I can say that few of these images seem real to me.
