Hi! I am looking for any opinions on Kodak T400CN in 5x4. As I want to do only o ccasional architecture/landscape in B+W (I normally shoot transparency) I am con sidering this film in preference to procesing conventional B+W myself. I've read that grain and tonal range is excellent but sharpness is inferior to convention al B+W films. Is any sharpness difference noticeable with print sizes no larger than 16x20? If chromogenic films are as good as they claim to be, why are they n ot more popular? Any comments gratefully recieved.
