I'm trying to keep E6 tungstem totally out if the grave. I have a 100' roll of Ektachrome 160T gifted to me a month ago, expired 6/1999. Storage unknown. Tests so far as being between ei40 and 80 under 3200K, clours off a touch too.
I also have a cache of ept 35mm, and almost 100' of way slow Ektachrome SE dupe film 3200K for duping c-41. Also about 200' of Fuji CDU-II slide dupe that is also fun to shoot under daylight or teungsten with the rught filtration (it alsway needs some)I. It is kind of like a 6ei astia, so when you want low contrast with no DOF with mega light, or the ability to shoot long shutter speeds for creative blurred moving subjects it is gret as well.
