Note on Kodak films:
Kodak was also coming out with a new Ektapress line:
PJA-100
PJB-400
PJC-1600
Later in 2000, they again upgraded the Ektapress line to PJ-100, PJ-400, and PJ-800. I remember using those films once.
Kodak also had an E6 Ektachrome called EPZ-100 in addition to EPN and EPP. I don't know what that was. Perhaps it was their warm-balanced version?
