70mm Film FUN up ahead

Wjlapier,

I chose glassine pages, I used to use Hasselblad and Paterson Glassine pages so I thought I would try these. You could also choose vinyl, like the VueAll and Printfile 70mm pages. Acetate also available, those are for transparencies, really.

These are oversize 120 pages; the overall page dimension is 10 1/4" x 12 3/16".
The 70mm film fits with plenty of room to spare; the individual strip openings are 2 14/16" x 9 7/16". I can fit three of four 6x6cm strips in these pages. These pages are big enough to accommodate 6x7cm, and even 6x9cm, I believe.

Glad I found these with Jakes help.

Hasselblads and Linhofs are beautiful precision cameras that are joys to use. Build qualities fit for a King. And the 70mm components are sometimes selling for no-money type prices. After all, nobody shoots 70mm, right???

I just love the klip-klop sound of the Blad, and all the amazingly cool things you can do with it. Absolutely there is no medium format camera that is even close to the number of accessories available for the Blad. I call it the "Erector Set of Photography". LOL

My new Hasselblad A500 magazine by Nokton48, on Flickr

A70s sell for $30-$40 routinely which is very cheap considering what they cost back in the seventies and sixties..

Dan, how much film is pulled through the cassette before the counter starts at 1--the A70 back. I waste so much film with the Graflex RH50 back, not so much with the RB 70mm back.

Remind me what the mod is needed to the Hasselblad back so the cassette can pull unperforated film and the counter works.
 
With my A70 Hasselblad back there is about 1 foot or 30cm of leader at the beginning. Not much we can do about it. It's useful for loading processing reels.
I'm about do do custom made roller for unperforated film in A70 magazine. It's quite simple replacement of gear in the magazine insert. You don't even need any tools for it. You need just one roller with rubber O ring outside.
Are you interested in one? I still need to contact local machine shop for quote. They did all custom aluminum work for all Tom A projects.
Will see how much is minimum order and how much it will cost. I have some unperforated 70mm Maco 25 to run thru.

Here is the original A70 Instruction manual. I suggest you read it over, it's not difficult to load this thing. But you need to be informed and make sure everything is "just so" for trouble free results.

A motorized EL or EL/M amazingly costs less than a hand crank 500C or 500 C/M. Click-whir. Click Whir. Click Whir.

I'm interested. I don't have a Hasselblad rig just yet, but might eventually--again.
 
Sorry, you don't have anything from Hasselblad or you don't have 70mm magazine for it?
In mid '90s I worked in portrait studio and we used RB67 for all studio stuff and Hasselblad's for everything outside. Both's systems produced great pictures. Mamiya's never seen any service. Hasselblad's need to be professionally maintained for proper function from time to time but nothing major. We were using at least 10-20+ rolls of film every single day, mostly with Hasselblad's. Studio had dealer status with Fuji film Canada. They will deliver film and paper to us by truck a few times a year.
Unless Mamiya's bulk and weight is issue with you there is really no reason to have both systems. Both are superb!

Hasselblad says you need to pull about four inches of film out of the cartridge, to thread up the A70, and that seems about right. And then you have the leader while you winding to "1". But honestly I've never measured how much at the beginning of the roll........... It usually gets cut off and thrown into the trash when I hang film.

I cut my really big 70mm film runs into strips of 12 exposures, and hang them on a wire I strung up in my basement, with wooden spring clothespins. I put plenty of clothespins onto the wire, so I can hang a lot of film. Simple and costs practically nothing.

Dan, do you shoot blank frame or two between each 12 exposures to have some space attach film to dry?

Hi Goran,

Nope I just put the wooden clothespin on the bottom of the film very carefully. Not much room. So far I have not had any problems. No blank frames between twelve exposures. Not has any issues so far.

On my drying rope I have vertical space for around 21-6x6 negatives. On my 100" SS reel I can fit around 42 shots, so i make one blank shot at #22 so I can have free space for clips.
 
GEAR ALERT: I hit the BIN on a Unicolor motorized Roller being sold "as-is" for $29.99.

Seems like a probable bad electrical connection. The seller with 100% positive feedback reports that when he initially tested the unit nothing happened, but after manually spinning the rollers he did get the rollers to spin under power.

So let's see if I won the lottery on this one.

Are there any plastic Patterson type reels for 70mm? Not a big giant one like the SS reels I see sometimes. Still having the hardest time getting the Rollei 400 film on the reels. First time I did this was fine. Second time the film bunched up inside the reel and I didn't know it until after I developed the film.

I use my test film outside the bag and can get it on the reel kinda OK, but in the changing bag the film seems to hang up on something. Inspection shows no nicks I can see. Bearings seems to roll fine. FWIW, the Rollei film is thinner than the Kodak Portra 400 BW/NC I have ( all 70mm ).

You won the lottery. Four screws remove the bottom cover. I've had them stick before but never after opening them up. Piece of cake.

70mm 2502 Jobo Reel by Nokton48, on Flickr

Jobo 2502 70mm Reel Modification by Nokton48, on Flickr

This a JOBO 2502 120/220 reel, that I cut in half (through the center column), with a hacksaw. I slipped on an EFKE 25 Plastic film can (which I cut off the end of) and glued it together. It works surprisingly well. This will fit JOBO 2500 series tanks. I have a Multitank 5 and 6. I have found only the EFKE 25 film cans will tightly hold together the JOBO center columns.

This is the lazy slacker way to process short runs of 70mm film. I use a Unicolor Uniroller to spin the Multitank. "The Poor Man's JOBO Processor". LOL
 
I think my reels were dirty. Loaded some Portra 400BW from the Mamiya 70mm back I shot with the Universal yesterday. After a good wash the film loaded just fine like 120 does.



I have another universal body that has a broken RFer so I'm thinking of making a "flattop" with it. The 70mm back, a 65mm lens and it's a compact wide shooter shooting 70mm film :cool: Way more compact and lighter than the RB67 I have.
 
It looks to me like 35mm SS reel
For film testing purposes I slit 70mm film to 120. Its way easier and I do not lose leader length for A70 magazine

Michael (Europanorama) made this 70mm reel from a 120 SS reel and a wooden dowel. Or is it a 220 reel?

The Unicolor Uniroller arrived Saturday. It seems the internal reversing switch binds up the motor and drivetrain, otherwise everything works.

I performed a wet guaze cleanup. My forensics is that some people mod their Unirollers by making the reversal switch manual and external. This suggests that this problem I have with mine is not so uncommon. My thinking is I might remove and disable it totally as I can always rotate the JOBO 3013 orientation 180 degrees manually.

Here at work I will replace the roller O-rings with new ones. The JOBO 3013 seems like the ideal size for using the Uniroller. The seams for the lid and base are outside the center cylander body that is captured by the rollers.

If you guys don't mind, could you share your workflow from exposed film to your scan? Do you have a darkroom or do you use a bag like me?

Myself, I take the exposed film and do all the transfer from spool to reels in a changing bag. Same bag for years. I use Patterson reels--there is a photo somewhere in this thread that shows two different ways to use the Patterson reels. I use this one:



The way I have the reels set up it's almost using the whole reel tube so I use ~700ml of chems. So far, I'm pretty happy with this workflow.

I'm looking to get a slitter or make my own to cut down some of my Portra 400 to 120.

Scans are done on a Epson V500 using a modded 35mm film holder--that was a great mod idea from Dan I believe. Vuescan to finish the scan and PS to resize and sharpen as needed.
