Complete Guide to 70mm Film

[rhizomeblur]

I have an RB67, size isn’t exactly a big concern lol. Plus, I got it for $10 with a set of cassettes, well worth the 98% discount compared to the actual backs you can buy on eBay I think.

Ha, good point! And yes, that's a big cost savings!

Well, I got my 70mm x 15 ft spool printed. Bad news, it doesn’t work. It was too wide at first, and then I tried sanding down the middle part, and now it’s too small… gonna have to see if I can make an adjustment in CAD and figure out how to get it reprinted since I really don’t want to ask the guy as my school to reprint it (again…)

If you send me the STL, I might be able to give it a try. I have some 70mm, so I could at least trial fit.

Yeah I can send an STL. I might make a few adjustments to it.

Played around with this some more. Yes, it does work, and it does hold an entire 15’ roll of 70mm. But it is extremely finicky and I do not have any confidence I could load this in the dark.

Could you try making the inside film tracks undulating, starting with the current starting place as is and a mm or two reaches like a wave in an old fashion apron ribbon, so it'll hold the film in place but able to cope with various widths in general, without the need for such fickled precision?

Ilford has started their ULF for 2025, and I noticed they have 50-foot rolls of 70mm in either no-perf or double perf emulsion-in. Have to be manufactured in multiples of 15. I'm going to be looking for a place to buy a roll or two. @rhizomeblur Zach - any plans for Mercury to participate? I think, based on last year's ULF campaign, that the FPP will likely accept orders. Anyone else know of other retailers that might?

Freestyle photo does, for 70mm they only show for Ilford HP5+

Oops, I didn't put down the emulsion. But, yes, that's correct. Thanks for the pointer - I love Freestyle!

I got a big roll of fresh 70mm film today! I’ll only be keeping 150’ of it, but still!


Also, I may have a lead on some frozen 70mm, both color and B&W. Mostly Portra 160NC, but also Vericolor III and Plus-X (type 2 perfed). There’s a lot there, so if anyone here wants a 50 or 100 ft roll, feel free to ask. I don’t have anything specific yet, very tentative at the moment, but I figured I’d let you guys know before I put it in the classifieds as 120/220.

If you get a good line on Portra, I'd be interested for sure. Thanks for posting!

Yeah, I’ll PM you.

So far it looks like 300’ of Portra, 100’ of VPSiii, and 1k’ of plus-X perfed is what I’d be able to get. From an huge film stash their father had, all been frozen. Trying to figure out what they want for all of it, but even without a bulk discount it’s a good deal.
