B&W 70mm film with dark teal base
I recently got a 70mm film loader with some film still in it. The base of the film on the exposed leader is a dark teal. I can't recall seeing anything like this before. Anyone have a guess as to what type of emulsion it is? I'm guessing a Kodak B&W aerial film, but which one?

Foma 400 has that kind of color, but that's probably not what you have.
This may be obvious, but why don't you snip off a bit in the dark and develop and fix it in a tray. That will make any edge markings show up.

Obvious to the intelligent, perhaps . . . dang.
Thanks.
I haven't checked out the Kodak site yet, but hopefully all the development times are close.

You will probably be okay regardless of the time (within reason). Since you are just looking for edge markings, I would start with something a tad on the long side and if they block up, which I find hard to imagine, then you can cut back. I have never developed film long enough to block up the rebate, so I think you are good.

Two minutes in Dektol should do the trick!

Why don't you cut off a short strip, develop it, and check the edge markings, if any. Most major manufacturers identify film by small print on the edge of the film, with at least on mark per foot. Any reasonable black and white developer for any reasonable time should be good enough to develop this information.

70mm film loader
WHERE did you find a 70mm film loader?
I assume it's a bulk loader.
Been looking for one.
Thanks,
Steve

Guess that thread's a few years old, Steve..! But they do come up on ebay from time to time for about $100, which isn't bad, considering you can occasionally find the film for almost nothing.

70mm bulk reloader
Sparky,
I've only seen one on eBay lately. I was floored at what it sold for!
I had no idea! I remember seeing them in old photography catalogs in years past. If I'd only known then what I know now.
I've searched for 70mm film and noticed that about all you can find is non-perforated. If my memory is correct, those loaders had spockets that engaged the perforations on the film, like the 35mm loaders do.
WHERE can you find perforated 70mm film?
I truly wish that someone other than Kodak made 70mm film.

Prices vary quite a bit on ebay for the loaders. Mine cost $1.04 -)
The loaders will work with either perforated or not. I'm not sure anybody still makes perforated film. OTOH are you sure you need perforated?
The Graflex 70mm back takes unperforated. I can't remember what else.
Efke a few years back cut some 70mm. Maybe if enough people were interested they'd cut more.
