What do you know about the edge printing on Kodak Vision3 films?

Hi everyone!
Great discussion above!

I could use help in identifying this mysterious Kodak film. I believe it’s a motion picture film but I couldn’t find anything about it online using the edge-print code. It is “K•ODAK 26 12” as it shows in the attached image.

well K'ODAK means it was converted in Rochester. perhaps if you could give us some more background information we might be able to find where to look. also the picture makes it look like the film was not 100% fixed.

Are there any other numbers except what you posted?

Thank you! The lab had this film in storage for a long time. The operator said that the reel was partially exposed by accident during storage but it seems to have hardly effected anything other than the edges. The container it came in has no identifiable information about the film origin unfortunately.

I was planning on using this film for testing cause I can get lengths of it for a very reasonable price. A 100 feet of this film would cost me about the same price for a single 36 exposures roll of ilford pan or HP5.
They tried shooting it EI 100 at the lab and got very thin negatives despite developing it in D76 (stock) for 30 minutes.
I estimated its ISO at 12 and developed it for 25 minutes @ 20° C and got the negatives shown above. Negatives turned a bit too dense so I think it’ll need to stop down exposure or a slightly decrease development time.

As for the edges, I tried refixing the negatives in fresh fixer but that didn’t help much, unfortunately.

Sounds like it may be some kind of duplicating film. Is it panchromatic or orthochromatic?

Not that I can find. It seems that this is the only thing printed on this strip. I’ll shoot another roll and see if I can find more on it.

I can’t tell. Someone on Reddit suggested that it might be X-pan but they can’t be sure.

The edge markings appear with considerable space between. There may be additional markings elsewhere on the roll. However, the K*ODAK marking suggests this is pretty old material and the edge markings may be more rudimentary than they are today.

I can’t tell.

Photograph something red.

Usually Kodak films that start with 2 have a special purpose - for recording sound, for recording subtitles (yes, there are those), for duplicates ... It is impossible to say exactly what this film is, but usually this are low-speed films with high contrast.

Even current film still has the mark between the K and O, (and is now only made in Rochester. the dot is so small you might need a magnifying glass.

the format of the printing reminds me of some print film where the last set of numbers is the year of manufacture. if it was 2383/3383 (can never remember which is 16 and which is 35) you might get something that slow, with KS perfs. the film itself before processing whould be a puplish shade with an iridesence on the back. the three colour layers whould each be sensitive to one colour and so it might look pancormatic if developed as black and white.
