Help Identifying Film

[Keomitchell]

Hello folks.

I recently bought a new bulk loader that has a roll of film already in it. I'm skeptical that it is still good, ie expired or exposed to light, but re-threaded the leader and spooled a short roll of five exposures at different asas just to figure out what asa the film is. It was developed in diafine and resulted in a completely black negative. I haven't used Diafine before so I decided to take the raw film stock and develop it unexposed in ID11. I got the same result completely black negative. I'm waiting on a refill of c41 to test the film in it but while I wait I thought I'd at least post a picture of the film.

I noticed that between the sprocket holes on one side were holes that I don't usually see on the film I've used before. I am hoping that maybe one of y'all could recognize this trait and hopefully help me narrow down the possibilities as to what film this is.

Thanks in advanced and have a great one.

Cut a piece of film in the dark and develop it. The rebate [edges with the sprockets] should tell you what type of film it is.

Hello Keomitchell and welcome to APUG. Never came across film like that so cannot help there. Interesting.

I've seen that perf pattern before, but danged if I can remember where!

There must be a way to overcome that total fog. Let me think on it.

Sorry.

Thanks for the welcome.

Yeah I haven't encountered this pattern before either and I thought it was odd but also a good clue. Side note, that is just a raw strip I cut from the spool, hasn't been developed. I was hoping that if I developed it I'd at least get some indication on the transparency as to who made the film but that didn't work out. Hurry Mr. Postman I need my chemicals!

That’s motion-picture film, most probably color positive stock. Agfa-Gevaert used to have these four-perf. interval circular holes with polyester-base CP 30. Too bad the film is exposed dead, else you might have been able to read a manufacturer edge code.

FWIW, I've seen that hole pattern on processed Kodachrome film ? (Though I doubt Kodachrome was ever available in bulk rolls to the general user ? )

A little sad update.

Last night I was able to head to a friend's to process in E6 and C-41 and it resulted in the same results of the emulsion being completely dark. This means that the entire roll had been exposed to light. I'm not too bummed about it because the entire package of bulk loader cost about 5 bucks not including shipping. Anyway, I popped the reel out and it is a Kodak film, the spool has the brand on it, but I'm left to wonder what sort of Kodak film is it? I know that it isn't Kodachrome, there isn't any remjet on the film.

The film that you have is most likely one of the four Motion Picture Black & White Films manufactured using a punch hole every fourth perforation on one perforation track. From the color of the stock (solarized), it would appear that you have either 5302, a Black & White print film, or 2360, a low contrast B&W print film. Kodak added these additional holes as frame line markers in February, 2004 when they eliminated the equipment that produced ink application frame-line markers.

I've seen those holes many years ago, but still have no clue as to where.
