Helen, thanks for the insight. A question tho; What has been your experience with NPZ pushed and printed. I've a couple of rolls in the freezer that I just can't seem to get around to using. And if I may ask, what was the subject matter causing you to use the film. I'd love to use it up for some early and late night work downtown, and am wondering if I'll have a problem with reciprocity as well as contrast. I'll need to scan, print and sell.
