In my experience, T400CN yields the same "extended-red look" as Tech Pan in the rendering of colors. I've displayed prints from Tech Pan and T400CN side-by-side and aside from the differences in grain structure and contrast (minimized in printing), the rendering was similar enough not to jar my sensibilities.(posted 8890 days ago)Unfortunately, my experience with both films is that lips tend to be de-emphasized (just checked a bridal portrait to make sure). Also, the tonal scale on T400CN is much longer than any other film I've used. It does look very different compared to traditional films.
Your print-tone comments sound as if the T400CN you shot was printed at higher than normal contrast.
