Seduced away from Tri-X by very favorable pricing and the fantastic reputation J&C has earned with its many loyal customers, I bought a small stash of J&C Classic 400 35mm film. So far, I like the film a lot but I find it is definitely different from the modern Tri-X. I'm treating it exactly as I do 400TX. That is: rate the film at at EI-250. Develop in HC-110 dil. D, 20 deg. C, 6 minutes, agitate 10sec / minute. After just three rolls of Classic 400, I have the following observations: The spectral repsonse of Classic 400 appears to be quite different from that of Tri-X. Tri-X gives finer grain Classic 400 appears to have slightly less latitude Although not quite as robust as that of Tri-X, Classic 400 emulsion is plenty robust. About on par with similar offerings from Ilford. ALl in all, it seems like a winner. Like I said above, I'm still not getting it quite right but, it does look promising. Anybody else have hints or observations on this film?
