70mm Film FUN up ahead

I just run my first test of 35mm Maco Eagle AQS (expired on 03/2014) film in Rodinal 1:50. That film is really 50-100ei at most! Very low base fog! Not sure how this emulsion relate to current 70mm Rollei 400, but somebody in Maco was super optimistic.

I looked yo the data sheet for Rollie 400S, and the base is 100 um or 0.1 mm, so basically the base thickness between the two films is the same.

I imagine a film cut would hurt like a mo-fo.

I promise to be careful. Loading 400S into 120 and 220 reels did take some extra care. Just had to work slowly.

The thin Estar used in this material is differently difficult to the thin polyester used for Aviphot.

We will send positive thoughts. Keep any cuts clean until they heal.

Marty,

Thanks again for the warning and safety hazard.

There seems to be an element of danger present kinda like machining titanium instead of steel.

On the Watson 70 bulk loader, the countdown from 6 to 0 is for each cassette. I've only used the metal core index and only on 100' rolls. When you load in a fresh 100' (and doing the math of 6 x 15ft) you'll notice the indicator is above 6. I usually spool off that 10ft into a cassette and use it as a experimental roll. Then on the next cassette, when it goes from 6 on the indicator to 5, that's another 15 feet loaded in. You can count the turns on the crank too. I don't know how to account for 150' rolls, with a thinner base. Some feel the indicator arm can scratch the film and remove it (plugging the hole). I have 2 of these bulk loaders, one the spring broke on, so I have to manually move it over from time to time to check on the indicator. I guess that could be a way to not scratch the film, move it out of the way for a few dozen cranks, move it back left to check. But I haven't seen any proof that it does/can.

Thanks Arden3, that's very useful info. I purchased mine with film in it, and the counter was on 6. I have loaded a cassette by counting turns in order to get approx. ten 6x7 frames for testing. And the counter is now slightly below 6. It did not occur to me that it counts the number of cassettes as 6 multiplied by 15 is 90, and the rolls come in 100ft.
 
Would anyone be willing to share what they are using for developing formulations?

I’ve been doing stand developing on my Kindermann tanks. In part because of the volume of 2 liters (1980ml water, 20 HC110) and because my Kindermann is super leaky when inverted. Plus, it takes a bit to pour in and empty 2 liters of fluid. So, I worry about timing critical development. I do a pre soak at 68 degrees while I cool my dilution then pour it in, invert for thirty seconds. Put the whole tank on ice for 60 minutes. Rinse, fix as usual.

What are you folks doing? Anyone doing C-41 or E6? I guess 2 liters would chemicals would get exhausted pretty fast at a 6 rolls of 120 rate? Anyone extending their color chemicals to get more 15’ color rolls done?
 
I've been using ADOX Borax MQ (with replenisher) which I mix myself. I got the idea from TomA, it's a D76 derivative, with slightly decreased suphite. It's great with my Kodak 70mm Surveillance film, which I similar to the old original Tri-X.

Yes it takes over a mnute to drain my 70mm Kindermann. Luckily mine is water tight.

Legacy Mic-X from Freestyle is current go-to. Easy to mix replenisher, if you use it frequently (don't let it oxidize from inactivity) and it will last forever. My last gallon lasted me FIVE YEARS before I had to dump it. And it gets better as it "seasons"

My development times are -extremely long- with this stuff, like thirty-five minutes in stock solution. But that is an advantage when using the 70mm Kindermann. And it is cheap $10 gallon from Freestyle.

Dan,

Looks great. My intent was to mix ADOX MQ as a one shot.

My JOBO 3013 can fit three 15 foot reels and I can use a Kodak hard rubber tank with lid as a light safe for the loaded reels. My intent is to pre- fill the JOBO with developer and in darkness drop in the reels as pouring six liters of developer is not practical. This JOBO loaded with three reels and six liters of developer will be a monster tank for inversion, but pretty much will be like developing 18 rolls of 120.

The water stop bath and the fixing can tolerate the long pour times I figure.

Know that I work in a research lab and I have access to HPLC grade chemically pure water (Just H2O) that measures 18 megaohm resistivity. I use this most chemically active water to mix my chemistry and for my stop bath. This water is so pure that it will erode living tissue so it is not safe to drink.

Plan "B" is my Slacker's Brew, meaning Diafine. I have four 3 1/2 gallon Kodak hard rubber dip and dunk tanks. One of these tanks has holes drilled for use as a wash tank, so I need just one more. My testing of Rollie 400S suggests 125 ISO for overcast, and 160 ISO for high contrast sun.

I used 4+4 in an inversion tank for my initial testing using Rollie 400S in 120 as short test rolls, but this time (one extra minute) is for denser negatives for wet printing and also because I only invert twice a minute instead of the recommended three (basically I slightly underdevelope due to lower aggitation). I'm not sure yet of the time and aggitation using dip and dunk, but it seems like doing one reel at a time is like 6 rolls of 120 in a monster inversion tank.

Plan C is Rollie 400S in Rodinal, but initial tests suggest only 80 ISO. I use 50:1 dillution, and I would use the three reel JOBO 3013 as an inversion tank.

The Diafine gets reused and also gets better with use (increased mids) as it gets "seasoned." The ADOX MQ is cheap enough for me to use as a one shot, but there is a replenisher if you want to be mucho cheap. Rodinal, especially muy diluted is a cheap one shot.

BTW I like all these developers and the negatives made. The ADOX in Dan's negatives have a punchy tonality. The Diafine negatives I make are like HDR film with smooth roll off in the highlights, enhanced shadow detail, with a vast midrange of a larger format.

Pretty much the time and aggitation is what I use to dial in the mids because the enhanced shadow detail and the smooth fluffy rolloff in the highlights is what Diafine organically produces. Understand that the highlights kinda are like in stand development because the Part "A" gets exhausted. Diafine provides a profound compensating effect. When in doubt overexpose.

Rodinal 50:1 also has a compensating effect. Rollie 400S is really not a 400 ISO film (they lied) and Rodinal with slow speed films is kinda wonderful. You loose some film speed. Oh-well.

Know that I make negatives that are for wet printing so I like some density.

OFF TOPIC: I just secured a 6x9 Super Rolliex (120) that will fit my baby Linhof's. I also have a 6x7 Super rolliex (120); a 645 CINE for over 120 exposures (70mm); and a 6x7 CINE for 60 exposures (70mm).

This is too cool. With only two lenses I get many different FOV's by changing formats. I can also do sheet film: 2 1/4 X3 1/4 using Graphmatics; and 6.5x9 using Linhof double sided holders.

If anyone is looking for a JOBO 3035 tank and JOBO 3075 reel PM me and I'll forward you some contact info. This is a hard to locate item.

Also available is an unopened 70mm Porta 160, exp. 2003 and an opened Fuji CDUII bulk roll.

you mean the 5m-developping-system? i have listed it somewhere else. has a loader. i have it complete, not yet used. it uses 1lt chemistry.

Hmmmmm Not much photo activity over the last three weeks. Goran was nice enough to sell me another Graflex RH50 for $25 including shipping from British Columbia. I got it today and it's another beauty..... I will convert this one also from Graflex XL, to 4x5 Graphmatic. Very simple and easy to do. This will let me shoot two kinds of 6x7cm 70mm simultaneously, in my Plaubel Makiflexes. Which is a good thing for me.

Goran once told me he compared 120 versus 70mm Ilford prices, they were about the same. To me the advantage for 70mm users is the photo firepower. 🙂

https://www.ilfordphoto.com/wp/wp-content/uploads/2017/04/ULF-2018-Items_Participants-sb.pdf

Also Ilford has started their 2018 ULF Program, the deadline for ordering is May 25 2018. I called my local Ilford Dealer (Midwest Photo) and they quoted me $173.56 for fifty feet of fresh 70mm type II perfed HP5+. This year I will order at least a few. Orders paid up front, no cancellation possible. Delivery in Fall 2018.

Who else here is ordering 70mm Ilford HP5+????


Graflex RH50 70mm Backs by Nokton48, on Flickr

New back (unmodified) on the left, modified back on the right. Very easy to do.
Click to expand...
Nothing to be modified, simply removing the XL-frame on the left. i have both. I have an idea for 61.5mm film(cut down 70mm) loading in Kodak-70mm cartridges. prototype was working. Am i right counter can be zeroed on RH-50, so very long rolls can be mounted. Technical Pan was available in 6.1m length. i could load 6,5m of Vericolor HC. with PEO 0.06mm even much more can be loaded. Holgamods promised 3Dprinting it cheaply. If anyone in the USA could send Randy Smith two Kodak 70mm-cartridges and some cut 70mm-film. is there a tool to wind film spools manually in 70mm cartridges? i promised him Linhof container but i cannot give mine and hard to get. maybe he is allowed to reprint.

Nice!

I need to find another way to use reels and a tank. The Patterson reels seize up when I load the film ( something to do with the bearing I'm sure )--again, I wonder how 220 can be loaded in these reels. Maybe I'll have to buy a Nikor reel and tank and learn how to load SS reels. I ruined a few photos since the film wasn't loaded properly on the Patterson reel.

BTW, awesome to acquire the Trix400 in 70mm. I'm about to buy two more spools of the Rollei 400 and stop there for a while--lol.

Stupidly, I looked at a Hasselblad again. While I can carry my RB67 around just fine I'm wondering about a smaller lighter solution. I thought about the Mamiya Universal with the Graflok back adapter for the Mamiya 70mm back. I have the Universal and the back fits but it's hard to see the viewfinder with that big back sticking out. I'll probably stick with the RB for a while--the glass is so good.

Even more stupidly, I've been looking at Linhofs! :bang:

Anyway, I'm having fun and to me that's what it's all about.

you must rinse the reels with dishwashing fluid. a lot of discussions about this patterson-problem online.

Spools Beatty Coleman Transet #2 by Nokton48, on Flickr

These are the spools out of Transet 70mm Back #2. The original Beatty one is marked "ANSCO, BINGHAMTON, NEW YORK, MADE IN USA". The yellow one is a generic 70mm plastic inner 70mm film core, which will work as a takeup spool ok. It has a slot and the film can be taped to it in the dark.

My plan with this is to shoot 20 exposures and then unload it in the dark onto a 220 JOBO reel for Mutitank 6 rotary development.
Click to expand...
I have a lot of specifications also for 70mm-spools- from ilford and kodak. pls specifiy data of these Transet-spools. I have the Longroll 4x5-70mm back from Korona where only the rigth spools are matching. i dont trust this approx. 6x9-back regarding flatness. 240 images depending thickness.

Sounds and looks like you are getting there! Excellent news.
I was surprised how quickly the 70mm Rollei 400s arrived from Germany.


Nikor made a film loading machine, too. See here:

Linhof also a darkroom-loader for 126 and 70mm films. I have one. someone sold multiple ones very cheaply. it seems a speculator bought all of them- maybe 10 or 6 were left. at least 10 years ago in germany.
one would only need it for 70mm when longer than 100feet/30,5m are involved. otherwise the Alden 70mm loader is the way to go.

I have these. the producer had huge problem with taping it. for long roundshot-panoramas best way is cutting one side for easy access. i was using a weight to let the long film slipping in... big pain gone when one side is open. seitz told not rolling panoramic films....not feasable for me.

The Graflex back was modified with a NPC Polaroid mount for the RB67. I didn't know what I bought until I read about folks using Graflex backs on the RB67. I bought the back for the cassette inside and maybe shooting 70mm in a Graflex camera. I didn't even pay attention to the mount. A little research and I finally realized it was a modified job and the mount was from a NPC Polaroid back. Aside from the leatherette peeling off it's in great shape and like you said it can pull unperforated ( and perforated ) film through it. I'll finish the roll tomorrow and see how well the modification worked.

I think what I might start doing is fill a cassette with film and use the counter to count off 12 shots at a time.

Thanks for the heads up on the roll of protective sleeve.

The 70mm back for the rolleiflex 6xxx is a Mamyia RB 67/70-conversion. very hard if ever to get.

My Graflex Rapid Vance 70mm film holder arrived today. It took about an hour or so to convert from Graflex XL, to 4x5 Grafloc mount, and to clean it up and restore it, including new foam inside, which disintegrated into powder when I touched it. So this would fit a 4x5 Speeder or anything that takes a 4x5 Grafloc back.
Click to expand...
where to get that foam? on one its gone. i have both versions. if with
XL-frame just remove it to get 4x5, am i right?
