As you all know, I like to take my chances with way out of date, questionably stored, off-brand, unlabeled films. I just got a couple of said films off of the 'bay, and I'd like some advice on how to expose them.
Here is the auction. The pictures don't show all of the text on the canisters, so here are the relevant details. (side note: why have manufacturers never written the expiry date on the roll itself? would save a lot of hassle on these unboxed films)
Roll #1
Clearly it is respooled Kodak 5247. It says that it can be exposed at ASA 100, 200, 400 without filter for negatives, slides, and prints. FOR: daylight blue flash, strobe, tungsten. When processed through MSI [insert addresses here]
Roll #2
3M color slide CS20. ASA640/29DIN. Artificial light 3200K. Process E6.
So ... what am I looking at here? I found a
spec sheet on 5247 that seems to indicate that its natural ISO is 125, so I assume that if one shoots it at 200 or 400 it would have to be push processed at MSI. Since I tend to like movie film underexposed by a stop, I may try exposing it at ISO 100 to maybe make up for poor storage conditions and age.
The 3M color slide film looks to be high speed E6 film, which I tend to hate. Also, I usually overexpose E6 film 1 stop and then develop it normally in C41. I know that some high speed E6 films are meant to be push processed when shot at box speed, and I'm wondering if this is one of them, and if so I'm happy to shoot it very slow so I can develop normally in C41. Unfortunately, no real bracketing possible here because it's one isolated roll and only 20 exposures.
