Well, you may be right. I don't know. But there have been some pretty good reviews of T400 CN film, which support my observation of the great range of this film. If you have some lab test to refer to, I would be interested in that. But, really, I think that Tony made the critical observation: you have to adjust the curves to exploit the dynamic range. The dynamic range it can handle is so great that the mid-tones are flattened until you tweak them to get where you want to be. But the information is there on the film if you want to exploit it. Really, I am a relative novice with this film. But it is very interesting to me, as someone who wants occasionally to make B&W images on film and scan them to produce prints. Supposedly it is pretty good to 1600. Here are a couple links with some review of this film. http://www.washingtonpost.com/wp-srv/photo/essays/vanRiper/010427.htm http://www.capla.org/98_nov.htm Berry ---------------------------------------------------------------------------------------- Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
