I'm hoping this becomes a discussion with samples.I was gifted several expired rolls of BW400CN, but gave them to friends to try film out (complete with loaner film cameras - one of the joys of a collection of cameras is sharing that collection). I find the idea of paying for B&W development uncomfortable because I have all the stuff to develop regular B&W myself (let's not forget: I'm cheap). I also assumed that because it was C41 processed, it would be lower quality. I was surprised to learn that Kodak considered the 400CN to be part of their professional film portfolio. Although I haven't seen any prints from the 400CN yet, I was rather impressed with how the 400CN filter in DxO Filmpack 3 renders images. I'm now much more interested seeing 400CN images. And I'd love to hear people's thoughts on using it vs using other ISO 400 B&W.Does it have the tolerance for over exposure that so many colour negative films have?
