We'd all like more dynamic range, but the sensor technology (CCD/NMOS and CMOS) really can't be crafted to respond like the photochemical reactions can in film. I'm sure this will be figured out eventually, but it's been this way for a long time- interesting time to be alive, that's for sure. Whatever the next sensor technology is, I wonder if more dynamic range will mean more "film look". -R > --- Ryan Brooks <[EMAIL PROTECTED]> wrote: > >> Jack Davis wrote: >>> This is why I ask for a review.
