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.
