70mm Film FUN up ahead

Here I have loaded a full length "dummy roll" onto my new Jobo 70mm reel. Actually I think it would be useful to have more than one of these reels. This will fit the Jobo Multitanks; even the single Multitank 2 one I believe. Will have to check that. I know it will fit my Multitank 5 and Multitank 6. USEFUL!!

Dan,

If that is the JOBO 3075 reel that can handle 15 feet of 70mm film then the correct JOBO tank is part number 3035 which holds 1.5 liter.

There is a JOBO 5025 loader that completes the kit, but I wonder how easy or difficult it is to load a big reel like that, and also how it compares to the stainless steel reel since you own both.

I'm moving forward also. It seems that the Rollie 400S when bought in a 70mm 100 foot roll makes a 120 equiv for only $2.50, so this is the most cost effective way to shoot 70mm, especially if processing is performed by me.

The good are many: 400 ISO can be pulled to 100; likes Rodinal for convenience and easy one-shot using a liquid developer; clear base for scanning; fine grain; high contrast; can be used as an IR film or standard film for flexibility; and is a fresh film that is available in 120 for testing and evaluation.

It is reported that the contrast is good for overcast or diffused lighting, but for high contrast lighting pulling film and using compensating effects are required for bright and high contrast lighting.

The bad: can be overly contrasty and ISO needs to be pulled for high contrast/bright lighting; does not respond to Diafine well; has to be ordered in Germany and shipped; and extra precautions required in loading (really-really requires subdued lighting or fogging will occur).

The ugly: to effectively use this film as an all-rounder some skill is required to somehow moderate contrast by either pulling the film speed, or creating a compensating effect. I'm not convinced that Diafine can't be made to work for moderating the contrast. Generally Rodinal accentuates grain in higher speed films, but not with Rollie 400S. One reviewer compared the grain to Delta 100. Hmmm.

The cost of a 5 pack of Rollie 400S-120 is $39.95 at B&H for a cost of almost $8.00 a roll, but 70mm ordered from Germany lowers the cost to $2.50 per 120 equiv. I think for testing I'll but a 5-pack of 120, but on a per roll basis it would be great to shoot 70mm because it would be cheaper than shooting than even 135 when you could buy Arista Premium (rebranded Tri-X) for $2.89 a roll.

Another thing that makes shooting 70mm cost effective is you kinda get a free gym membership.

Cal,

No it's not the 15 foot Jobo reel, this is the 35mm/120 #2502 reel that I have modified to take 70mm film. It will hold about 24 exposures give or take, like a roll of 220, or two rolls of 120.

I built it to accommodate a shorter piece of 70mm, like if I'm doing development tests. The good news is that I can still put the reel in a Multitank 5 or six and agitate it on a Unicolor Uniroller. I cut the reel apart and widened it, to fit the 70mm film.

I don't have the 15' Jobo tank or reel. But I do have the Kindermann, which is similar.

There are many compensating developers. One that immediately comes to mind is D-23, one of the softest working developers I know of. It's just Sodium Sulphite and Metol. You can mix it up using measuring spoons.

I like soft development and that is why I use Legacy Mic-X from Freestyle. I also make up replenisher for it using the old Kodak recipe. Available on the internet or ask me for it. Wonder how it would work with Rollei 400S? Hmmmmmmmm
 
I've had a question about the "Kodak Clips". If you are lucky they are inside your Kodak 70mm cartridges.

When I load 70mm (in total darkness!), I wrap the end of the 70mm film around the spool, then I snap-on the Kodak Clip. It holds the roll on the spool, yet allows the roll to come easily off the unexposed cartridge, and into the exposed cartridge, smoothly and without harming your camera.

I suppose alternatively you could use a bit of masking tape to accomplish the same thing?

This is some Kodak Portra I have on hand for dummy loading.

Finding extra Kodak Cassettes are proving to be harder than finding film.

Stefan,

I got one Kodak cassette loaded with unknown film with the 645 CINE, but it is missing the clip that Dan has a supply of. Masking tape is used instead, but this can eventually mess with the felt.

BTW the Linhof Patrone (70mm cassette) uses the Kodak body , but the spool is different and utilizes tabs that capture the perferations. I initially had difficulty, until I figured out that one must complete a full turn to secure and lock in the film into the spool.

Somehow I secured 7 cassettes: 6 are Linhof; one is Kodak; and two Linhof's are missing their spools.

Cassettes surely are difficult to find.

Perhaps this photo will better explain what I have done:

Jobo 2502 70mm Reel Modification by Nokton48, on Flickr


A short end (about 24 exposures of 70mm) may now be developed along with 35mm, 16mm (!), 120 and/or 220 film, in a Jobo Multitank 6 or Multitank 5.
This is a big deal to me! 🙂

Great for "clip-tests".

Dan,

I am considering a JOBO 3012 Expert tank. First off it can process 12 6x9 sheet films, and know that I have 10 Grafmatics for 6x9 sheet film. Secondly I have incoming three 15 foot stainless steel reels incoming with a Nikor tank that oddly has no light trap and is not a daylight tank.

I think I may be able to use this old discontinued JOBO tank as an inversion tank with my SS reels if it is 9 inches tall. I understand that Expert tanks are 8 inches id diameter so the 6 3/4" reels should fit. 2 3/4"= 70mm so I figure I need 3" height for each reel.

I can see down the line getting a JOBO processor that can handle Expert sized drums. For consistency, convenience, economy, and speed this seems the way to go. Likely that the SS reels will be limited to using the JOBO tank for inversion only.

One tank for 180+ 6x7 is great for me.

Here are my Jobo Multitanks, and also my sheet film reels.

I can process twenty-four sheets of 6x9cm sheet film in the Multitank 6.

These will NOT hold 2.25"x3.25" sheet film. I have a Honeywell Nikor tank for that.

Dan,

I was looking at FP4 in 2 1/2x 3 1/2. This is the sheet film size for my Linhof double sided holders, but the Grafmatic 23's I have take film that is 2 1/4x 3 1/4.

When they say 6x9 are they not saying 2 1/4x 3 1/4?

Also do you JOBO silver prints?

I am trying to flush out the big picture here and trying to understand how if one day having a JOBO processor could be utilized to my advantage and help support a lazy slacker.

Cal,

My 2509N reels will only hold 6x9cm. Since the others are a different size, they won't fit on these reels. They also hold 9x12cm and 4x5. Very high capacity processor, I can do 24 sheets at a time. Use it on Unicolor Uniroller, don't need the rotary Jobo ATL.

Not sure about the Expert tanks, I don't have those. I tray process B&W paper, up to 11x14. For 16x20 I use a Unicolor Unidrum 16x20

I would ask CATLABS to be sure. They are the Jobo distributor around here.
 
Here is another 70mm Omega D2 negative carrier that I have modified. This started out as a 6x6cm carrier, but I opened it up to fit my Beatty Coleman Transet Back. Notice the unusual proportions of the frame.

This one required a LOT of cutting and hand filing to finish up. Now ready to use.

This I believe is the Honeywell Nikor 70mm SS tank and reel. Similar to my Kindermann but SS

Dan,

I now have two of of these "spoked" 70mm 15 foot reels and a third stainless steel reel that resembles a Hewes 220 reel except mucho larger. I also got a Nikor SS tank, but it is not a daylight tank, and I figure it will be used as a film safe for a loaded reel.

The photograph above does not really present the enormous size of the reels, and two of these reels is about the size of a Baby Linhof unfolded and ready to shoot. Also the spoked reels are rather heavy.

I practiced loading 15 feet with a dummy roll. The only tricky part is the first turn. Getting that right is important because then everything else falls into place. It is no harder than loading a SS 220 reel which with practice is easy, the only thing is that this takes even longer because you just keep spooling film.

So having 3 reels is impressive. I still have to get a daylight tank that can hold all three reels, but to be able to process the equiv. of 18 rolls of 120 plus bonus frames in one tank is a huge time saver.

I'm looking into older JOBO expert tanks to utilize as my daylight inversion tank.

Looks like I can buy Rollie 400S in 120 for testing. Rodinal seems to be a good developer here, and perhaps I will try a semi-stand development to get a maximized compensating effect with a high dilution of 1:100. The Nikor SS tank I might use and dedicate for semi-stand development for an hour. Basically 6 plus 120 equiv.

Hi Cal,

That all sounds really good to me. Sounds like you are also making some good progress. There is a LOT to have to work out to make 70mm feasible. Not all of it it is such an easy task. But once worked out the rewards are major and really quite awesome. And you will be one of only a few to have the tenacity to see it through. I would think in NYC there should be sources for outdated film if you put your feelers out. Surely there are photogs out there with this stuff in their freezers. I hope you hit your own MOTHER LODE like I did.

I think the Nikor uses a regular SS 35mm lid which is removable on their 70mm tank. If you know of a metal shop maybe they could modify your plain flat lid to take a 35mm Nikor lid. The Kindermann is the same way; the lid for their 70mm tanks is a 35mm plastic Kindermann lid. It is also completely removable.

OMG OMG OMG!!! Look what Dad got me as a gift!!!! Nikor 70mm developing tank!!! These things are IMPOSSIBLE to find!!! #70mm #ilovefim #ishootfilm #mediumformat #nikor #film #family #dad #developing #winning #work #chemistry #116 #616 #yes by Stone, on Flickr

The Linhof cine rollex arrived today. It is in excellent condition. Even came with the cartridges. Interesting that it loads like a Leica M3 - though here it is top loading. I will have to scrounge for other cartridges somehow. May have to get those film canisters I see NOS on the bay. Now to get film.....

Here is a Guy in the UK selling 70mm Kodak Aerographic 2402. This film has been respooled into 120 rolls:

2402 Aerographic no 1 by Nokton48, on Flickr

Aerographic 2402 no 2 by Nokton48, on Flickr

Aerographic 2402 no 3 by Nokton48, on Flickr

From their website:

Here are the processing times for small roll that we have found from our own research:

200asa
HC-110 (dil A) 10 min @ 20c ~ Tested by us, makes lovely strong negatives
HC-110 (dil A) 8.5 min @ 20c for a less strong negative ~ Our Guestimate based on above!
Xtol 1+1 12 to 14 min ~ Tested by us, go longer for more contrast…
Rodinal 1+50 14 min @ 20c
D76/ID11 1+1 10 to 14 min @ 21c

This film looks very good to me. I have a roll of 70mm Plus-X 2402 Aerographic, and I'll have to try it!

HC110 Dilution A is pretty strong stuff. Great to know this info. I'm going to try this!
 
Nik and Trick are the shop I talked about earlier while talkingabout the ilford ULF ordering. Theyre actually about a 20 min train ride away from me and my usual shop. They have incredible service and stock and roll a lot of oddjob films. They also sell incredible minilab chemistry for a great price and about ten mins ago I just ordered 5L of said chemistry in RA4 for only £20.

You should have no worry ordering from them
 
Here I have test-loaded some old 70mm Portra onto the "70mm Dental X-Ray Reel". These reels are not expensive ($10 each) and an agitation rod is several styles is available. I'm thinking this might work well (three or four reels on the agiatation stick) in a Kodak 3 1/2 gallon rubber tank. Processing that much 70mm film at once would be awesome.

This reel with practice will work just fine. Sure can't beat the price!
