Your roll of film appears it may have been made in March 1987. Here is a website with a bit of information if you scroll down.

thank you Robert!

I'm sure it's b/w. I don't think it's a camera film- that would have the ISO on the can as above. I think it's a laboratory film for making contact prints.

The difference in speed ratings may just be down to differences in development. You are better off starting at the lower figure if you're using an ordinary fine-grain developer. It is likely to have lost quite a bit of speed. I would tend to assume at least 2 stops, which may make it inconvenient as a camera film.

I think "Tasma" is probably just a brand of Svema (also Ukraine).

Edit: This about a company that took over Svema's manufacturing. They have a film rated at ISO 3 to 6 which I'm sure is a print film.

mentions a b/w positive film. (It's still negative-working though despite the name).

 

Yeah, I think I might as well use it as print for the contact printer - will give it some tests. At this point 11ISO with 2 stops down it's definitely out of flexibility for me ? thanks!!

Thanks for this. I think I'm up for testing next week, printer and camera, it seems I can be expecting contrasty results! - even more with a D19 ?

Hi, this film stock seems to be "Tasma KN-1" (N, not H, it is Cyrillic ;))

I found some specs on an old website:

So the light sensitivity seems to be "12" and it turns out during Soviet times this manufacturer used the film speed scale ГОСТ.

The Russian wiki page "Light sensitivity of photographic materials" has a handy table that even mentions the KN-1:

But in this table it is the "Svema kn-1" not the "Tasma kn-1" (however, the "ТУ = technical specification" of"6-17-445-83" of both manufacturers seems to be the same?).

The table mentions an ISO of 12 but that seems rather slow.

So maybe this page is right when it says 32-64 ISO, as it refers to this same technical specification.

Also the film seems to be black&white. Given the slow speed of the film you may get some results out of it.

Correct me if I'm wrong.

You sure are a master of the research! thanks so much for this... at this point it most probs is 11-16 with 2 stops or 32-64 with 2 stops... I like the idea that it could still work as a B/W print as I do a lot of prints at the moment in the optical printer.

Thanks again for the info! learned a thing or two ?

Hi knowledgeable folk - hope you're doing great and in great health.

I'm in the search for ISO settings for the following film stock "TASMA KH-1 - would anyone know? - if you can find the expiration date that'd also be appreciated.

I'm doing some tests with the stock to check its state, but I need starting parameters first.

(context: from Ukraine - Released date March 1987)

Thanks in advance!!!
