70mm Film FUN up ahead

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!


See above ^^^ for the link to the reel manufacturer.

Sorry where is the link? Cant seem to find it in all of the text (dyslexia)
 
That looks promising!


So the 120 spools can be put in the 70 film holder in lieu of having to hand roll and load the cartridges?

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

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!

Actually they are just like factory-load 120 rolls. Just made from 70mm film.

So they will fit in a 120 back or camera. You could use that film in your Makina :)
 
I just picked up this roll of 120 respooled 70mm Kodak 2402 Aerographic film. This is shipping from Germany, this is the Guy selling the 70mm 120 respooled Kodak Color Infared. He still has some of that for sale. Cost for the roll was $13 including shipping to USA. I will shoot it in my Plaubel Makina III's and Makiflexes. :)

Nik n Trick also have thirteen rolls of this very same film for sale (probably came from the Guy In Germany). See their link above ^^^

Here is an email that I received from Dean Bennici, came all the way from Italy. Dean is the guy selling the respooled 70mm film re-rolled into 120. He still has some color Infared for sale.





Here are a few examples for processing this Aerographic Black & White film, but the film has a wide latitude and following processing times for ordinary Plus-X seems to have produced results for many users.

ISO 125 small rolls with agitation at 30 second intervals
d-76 (1:1) 6.5 min. @ 21c
HC-110 (dil A) 4.5 to 5 min. @ 21c
Microdol X (1:3) 11 min. @ 21c

160 to 200asa
Xtol 1+1 10.5 to 12 min @ 20c
Rodinal 1+50 14 min @ 20c

250asa - HC-110 (dil A) 10 min @ 20C
Hc-110 (dil A) 10 min @ 24c for a stronger negative

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

Dan,

I consulted with "Mr. JOBO" and it seems like I can cut down an early version JOBO Expert tank that is oversized into a custom size to accommodated my three 70mm 15 foot stainless steel reels. This way I have a daylight tank.

Some expert tanks have a cup instead of the funnel on the light trap, but I can get what I need from CatLabs to further customize my daylight tank. The ID of the Expert tank is 7 3/4 inches. Plenty wide for the SS reels.

I don't think acquiring film will be a problem. I am also thinking that since Ilford this summer will be doing HP5 for their ULF program that in 2018 they will hopefully doing FP4 next summer. This would be ideal for me. It would be time to load up the truck. Ultrafine partakes in the Ilford ULF program and there are no minimum orders. Their pricing is lower than B&H BTW. Time to load up the truck as they say.

All I need is FP4 and Rollie 400S and I can do mucho photography. Having three 15 foot 70mm reels is impressive. Major firepower.

Taking inspiration from this beautiful camera I found on Flikr, I have decided to build my own version. "The Sinar Norma Handy" camera!

Here I have acquired a Norma Auxiliary Frame (just for this project!) and removed the extra unnecessary pieces. I then removed the two Sinar metal male screws at the top and bottom, by removing the cotter pin holding them in. I'm going to add this homemade wooden pistol grip I bought on Ebay for $10.

I will drill a hole front top center of the grip and insert a cable release to trip the shutter on the 65mm F8 Schneider Super Angulon. Still need to find one in nice condition. And an appropriate viewfinder, and Bubble Level will need to be attached. I'm going to take my time designing and building this.

Here's the wooden grip.

My project thus far:

Sinar Norma Handy Parts by Nokton48, on Flickr

This Camera will take a Graflex 70mm RH50 6x7cm film back, or a Beatty Coleman 6x8cm 70mm film back. Also 4x5"/9x12cm :)


And here is the Sinar Handy Norma Viewfinder I think I will acquire:

And I just bought this cold shoe mount. All I have to do is tap out the Norma built-in shoe to fit the mounting screw on the cold shoe

If I take one of these apart, it would probably be a good fit on the "Norma Handy"

Easy to take apart and modify.

Camera building is FUN! :) Here are the results of my initial effort today. I figured out how I wanted to attach the grip, and that is done and I am satisfied with the result. Went to Lowes for parts and was able to get what I needed to do the job. A lot of metal cutting was required to get this right (trial and error). It takes 4x5 holders without too much juggling (for me). Here it is shown with one of my Linhof (springy pressure plate holders).
I'm not now thinking I want a bubble level; This camera will never be on a tripod. If I want straight lines I will use one of my Normas.This is going to be a work in progress. I like how this thing handles, this is my first experience with a "Handy". Onward and upward. Eventually I want a Norma era Sinar Grip, those tend to go for big Bucks $$$ Ten Bucks gets me going with this one.

The later Handy; The F Black bail mechanism is a lot stiffer than the Norma; I prefer the Norma mechanism myself. This will work fine with my Liscos and Fidelity 4x5 and 9x12 holders. :)

Great work, looks like a fun camera to use and I can image it makes great images!
 
I have come across a small problem, Ive gone to buy some 70mm film on ebay and all the the items that were there a few weeks ago leaving me with some colour or some Pkus X that "feels like it has half a roll left."

Obviously IR 400 is an option but I would like to have tried some plus X as im pretty sure what to expect. Any help in finding any?
 
I bit the bullet and bought a five pack of Rollei 400S in 120 for testing.

I want to see if Rodinal will work for me. One reviewer wrote that Rollei 400S is fine grained, and mucho contrasty. I'll see how Rodinal at 1:50 for 22 minutes moderates contrast, but for diffused lighting where the contrast is welcomed Rodinal 1:25 for 10 1/2 minutes.

Both at 400 ISO, but developed differently for contrast.

I'll also see how Rollei 400S responds to Diafine since it is a compensating developer. The author I mentioned above did not have any luck with Diafine, but because I have Diafine mixed and have so much experience using Diafine, I figure I'll give it a try. I'll report the good, the bad and the ugly.

The way I use Diafine is for a gentle push, but with Acros I shoot at box speed (100 ISO). I tend to over expose and then underdevelop, and I found the recommended film speeds for many films to be too high. I like denser negatives for wet printing and not for scanning.

My thinking is perhaps box speed (400 ISO) or maybe 500 ISO for the slightest bump. We'll see. I'm predicting that Rollei 400S will be more like Acros. 120 rolls of fresh film make it easy for testing. If all goes well I'll load up the truck and fill the freezer. For about $2.50 to $2.60 a 120 equiv in 70mm the costs are low like the good old days. BTW a roll of Rollei 400S in 120 is about $8.00.

the RR400s, I have never been able to get 400 out of it. in most developers it's a 100 to 200 speed film, even the 2 rolls i did in Diafine. best luck i had with it were pyro-MC at 160 or mixing some beutler also at 160.

by the way you can buy the film direct from maco in germany for like $3.75 a roll, much cheaper than anyplace in the US. 35mm bulk rolls are around $40. yeh you gotta pay shipping but if you buy around $125 US, then it's half the cost with shipping. check it out Cal.

They also sell new 70mm Rolls as well, including the Infrared film which is very similar the the rr400s

John,

Thanks for the post.

I'm using the two above links as a starting point. It does seem like Rodinal works well for this photographer. Martin does not like the long development time of 22 minutes for 1:50 Rodinal. He uses the times off the MDC. For me if I like the result I make up the time by either using a larger tank or 15 foot reels to make up the time by increasing the volume of film I'm processing.

I found Martin's method of minimizing agitation using Rodinal 1:25 for 10 1/2 minutes (the same as ISO 400) to pull 400S to 200 ISO interesting to gain a compensating effect. Also the reported small grain. In my own use Rodinal with slow speed films like Acros and Delta 100 maintain small grain. If I can get these reported results then this film will allow me to do mucho photography.

If I can get 400 Infrared in 70mm bulk that would be great, but if buying direct from Germany saves money, even for 120 rolls, I will do it.

I tend to focus on a single film and developer to maximize my results. For 135 I have my ways, but this work is more or less in making medium format as inexpensive as possible so I can scale up the volume.

I think i read 150 ft as 15 when i looked, oops that actually looks good. I need to work another week as ive only got £100 pounds saved so far.

I did have a crazy idea as Im being given a paper processing machine which uses rollers and a temperature controlled system of running paper through it, provided i cleaned the rollers and kept the lights off I could maybe run film through it with a bit of trying. It would probably result in scratches though but it might be worth a try.
