I was given two cans of double perf 16mm film today and I have no idea how old they are. I was hoping someone could give me a ballpark and perhaps some advice to go about shooting it.

The stock is Eastman Color High Speed Negative, number 7292.

I can't find a date on it anywhere, but there are a few numbers that I don't know what exactly they refer to. Above the stock name, it reads:


16 2R 7605(2994) EI ECX 451
7292-241-112 400 ft (122m)



and at the bottom of the label it says:


CAT 184 4182


Can anyone approximately date this film? When I shoot it, what should I expect in the way of fogging and loss of sensitivity? Any help would certainly be appreciated.

7292 was on the market from 1986 until 1992:

Even if it was kept refrigerated, a higher speed (EI-320T) film like that likely will have some fog issues and loss of contrast and speed after at least 13 years.

So what would be reasonable to rate it at to shoot it today? It was kept frozen all that time so perhaps 80 or 100?

First, get some processed to assess the fog level and perhaps even the full-curve sensitometry.

If the fog level is not too bad, rating the film at EI-160 might be sufficient. Expect an increase in graininess.

If you're more curious, there are date code marks too. http://www.sabucat.c...pg=datecode&z=1

Der....(that's English for Doh) you can only see the date codes on PROCESSED film. Excuse my brain.
