Actually both. I can't recall offhand seeing a 10-stop range in a single image, excluding light sources and specular highlights (which often zoom right off the scale--but you'd never realistically try to record detail in those anyway). Even between deep shadows and sunlit highlights, the differences shown by my spot meters do not exceed half a dozen stops or so in most cases, and I don't remember any specific cases of ten-stop differences, although I'm sure there have been a few almost artificially extreme cases in which they appeared. Even right here in front of my PCs, in a darkened room with a few light sources, I can get only about a 8-9 stop difference between the brilliantly lit white ceiling above a halogen lamp and the dark shadow under a desk. ---------------------------------------------------------------------------------------- Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
