Can someone explain 70mm film please?

[StoneNYC]

I've got 5 rolls of Double-X on the way. Spoke to Hewes in the UK, and they can supply most everything for 70mm. They even have a loader for their 70mm spirals. Any idea if this "loader" (doesn't look like a bulk loader), could be used to load cassettes?

Daniel.

Wait they have a daylight loading tank for their 70mm reels?? Are you sure?

The Hewes loader is a spiral loader not a cassette loader. It holds the spiral and has a tongue to put a little curl in the film so that it goes into the metal spiral neatly.

What did they quote for a spiral+tank ?

Wait this helps to load 70mm into the spiral once it's shot? So I don't end up skipping tracks and get film stuck together preventing the chemical from developing properly in some spots? Is that what it's for? I DEFINITELY need one!

This is from the Hewes website. I think they're just for spirals and the previous poster was mistaken. Anyone know how they work?

You can see they're for spirals because the cranks have notches to support the wires at the core of a Hewes spiral. And there's a place for the reel to be supported and have the film pulled off it and follow the metal strip (guided by the folded edges) onto the cranked spiral.

My question related to whether anyone had used Jobo spirals to do 70mm, since I have a CPP2 and lots of spirals.

Jobo #5025 = 70mm loader and guide
Jobo #3075 = 70mm reel 5 meters
Jobo #3035 = One-reel tank for above reel

Jobo #2517 = 70mm reel for 2500 tanks (film length??)

I looked for a year to find that tank, never could, Jobo certainly doesn't make them

First the ones on the site say specifically 35mm only? Or I remember reading that.

Secondly I don't seem to understand what "for spirals" means... Aren't all developing spools spirals? Am I missing something?

They're for transferring exposed film from the cartridge to the spiral, i.e. they are spiral loaders. They are not bulk loaders for transferring unexposed film from the bulk spool into the cartridge.

You can see in that picture several sizes - note the widths of the film tracks (the flat bit of metal) and the diameters of the little cartridge-holding sections.

Thanks, I was confused before, haha got it now, and yay! Can't wait to find out the prices... I'm now inspired again about 70mm

Thank you for correcting me (post #8)!
I never saw these before and thought they were intended for darkroom spooling bulk film onto cartridge reels.

Found this: developing 70mm in unmodified Paterson. Shorter lengths, obviously. I just tried the exact same arrangement on a couple of Jobo 25xx spirals and the gap between them is... 70mm.

So at least I know I can shoot & soup 220 lengths without a special tank.

Great Information!

I thought I had mentioned that 116 spools would fit 70mm?

Well glad you found a video that's neat

Neither Paterson nor Jobo refer to type116/70mm for their current reels. So that trick above adds to their compatibility.

Oh man I fail...

If you hadn't said that I wouldn't have gone back wondering what you meant and watched the video again... Or rather THROUGH... I had only watched the beginning, skipped to the middle, and realized he had reversed that end which I hadn't seen the first time...

I actually tried this without the second side at the bottom and it failed so I gave up on that haha I was so close!

Anyway I actually found a 116 reel that is self loading, I had already bought one 116 tank that sucked and would load from center but it was plastic so it was a pain staying in the track. Then found a self loading one.

I'm keeping the other one though bedside it's adjustable and I can do 110 in it I think.. At least I can do advantix for sure.. Though I'm sure it will be a PITA lol

Thanks polyglot

Had a reply from Jobo on 70mm x 5m

"Dear Daniel,
thank you for your mail.
In the moment we did not have this spiral but it could be in 6 or 9 month.
We have some customer wich asking this spiral.
My be ask in some time again."

Sounds interesting.

That doesn't really tell you much, especially since we were waiting for price info, and do they have the loader spool things we were discussing in stock? I'm ready to buy one now I have another roll of 70mm to process soon

I'm a bit confused as the former 70mm reel for twist agitation took 10m.
Will the new one be for rotating processing?
But anyway, good to learn that prodution seems to be cranked up again.

That 2517 reel for 70mm is listed at a german dealer, but not at Jobo, but with that trick above there should be no need for this.
But what lenght does system 2500 actually take?

 

[snaggs]

Stone, that quote I posted was from JOBO, not Hewes!

Will post hewes prcing and info when I get it. They already have the stuff. Here is what hewes said

"Hi Daniel,

I am away from the office until Wednesday, will send prices etc then.

We do manufacture 70mm loaders to complement our 70mm x 3 & 5 metre spirals.

Tanks however can be obtained from Richards of Hull"

Oh thanks! Sorry for the misunderstanding.

Have you tried Richard and Hulls? I've never heard of them...

I'm excited, and I thought I was the only one doing research, apparently I just stink at it...

Sounds reasonable on the Jobo; my guess is they might be considering moulding (and then warehousing) a batch of new spirals once the CPP3 starts selling, they're probably flat-out working on CPP3 stuff right now. Being that their quantities are so small (and therefore the staffing levels would be low), I assume they're just producing batches of one part at a time unless it's outsourced to China.

Hewes tanks I've not seen for sale but the price on SS spirals seems to be about $85 and $115 for 3m and 5m respectively - they're available in the US from non destructive testing outlets that use 70mm film for xraying.

One can also buy rugged $10 plastic spirals from the same NDT places but they're 3m (maybe 10') and 13'; there are no cheap 15' options. I'm going to try getting a couple of 13' reels and maybe figure out a tank for them.

I'll sell you my 13' plastic reel, I have one from NDT, it's not worth it for me, too much trouble to wind, I think it was $10 so I'll charge $10 for the reel and $10 for shipping if you want it?

You start from the clip in the center and work outward.

So it's not a twisting self-loader like the Patersons?

PS you'll lose money on offering $10 shipping to AU

There are many reasons that 120 and 220 were very popular formats for professional photographers but 70mm was not. 70mm was successful for applications that absolutely required a large number of exposures i.e. 70 and had the extensive engineering support necessary to keep it running. Examples are NASA/military/scientific applications and mass portrature.

120/220 is far better suited to satisfy the needs of photographers. Photograpers have an enormous number of variables to deal with when preparing for shoots and making photographs. 70mm adds unneeded complexity. Mechcanically the magazines are not robust. They require a great deal of attention if they are to be reused and daylight loaded. NASA used modified mags that were darkroom loaded by qualified technicians.

120/220 has the advantage of film that is factory spooled in a clean humidity controlled environment that is momentarily exposed to the environment when reaches the exposing film plane. Camera interface and film processing problems are very rare.

70mm has many opportunities for problems unless the equipment and materials are carefully maintained and used.

No not at all a self loader

Also, I am being a typical American and assuming everyone I talk to us also American...

I'll still sell the reel for $10 (US) plus applicable shipping, shouldn't be too much if I can go by weight.
