Chromogenic films are a little finer grained, but they have a couple of disadvantages for wich I don't use them. 1) Low contrast, low D-Max and high "fog". 2) The results change according to the man who developed it at the lab. 2) Very easily scratched (plus they tend to be even more scratched beacouse of comercial lab handling. 3) When you print it (contrast from 3 to 4,5 usually) scratches become very evident. 4) It has an ugly color (maybe only I care for this, but...).(posted 8378 days ago)If you want fine grain whith 400 ASA, expose TMAX 400 at 320 asa and develope in microdol-x reducing the time.
