GAF Arial film development questions

[StoneNYC]

Well, from the scant information, the GAF film may not be for USAF use. That is a guesstimate for now.

Our cannisters and rolls fit our cameras as easily as any other camera. I have some 5" and 9" rolls here AAMOF and they look just like film rolls.

What's "our canisters" mean? Do you work someplace I'm supposed to be aware of? Do you mean 5" and 9" tall roll film? Wow what is that even used in? I thought that big you had to use sheets because of needing a flat/even plane over such a large surface area?

I have quite a bit of their Hyfinol developer and Hyfinol Replenisher. Most is in Ansco cans, but I have a few branded GAF. It's a nice developer and pretty unique, but results not wildly different from D-76. I read some discussion about Hyfinol by Patrick Gainer a while back. He liked the stuff and tried to reverse engineer it (fairly successfully from the sound of it). I also have a bit of GAF Permadol; I believe that was their standard tank developer.

I can see how it would be interesting to find the manufacturer's information, but I don't think it would really be helpful. I have directions for the Kodak aerial films (which I shoot in Cirkut Cameras) and the directions for aerial use are nothing like what is needed for pictorial use. You just have to test and find the best EI and developing time for your use, as with any other film. You've got a good starting point, which is the hardest part. For myself, I'd want about a stop more exposure than the negatives you showed earlier. At that point you might, or might not, end up wanting a somewhat shorter developing time too (maybe 20 percent).

BTW, I shot some of that same GAF film in 9.5 inch when I first started with the Cirkut Camera back in the early 80's. I took one of the nicest black and white shots I ever got with the Cirkut on that film (already well out of date then). I imagine I developed it in D76, but don't really remember. It was very nice film that I didn't fully appreciate until it was too late to find more.

In case anyone wanted to see my mod for my daylight 70mm tank...

It has some light leak issues I'm working out. Still hoping an actual daylight tank appears that I can buy off someone, if they even exist...

Yea, pretty sure I metered wrong, or I Maybe should be shooting at EI 100... The date stamp of expiring nearly 30 years ago would put my stop correction (1 stop every 10 years right?) at almost ASA25... I think that's a bit much.... But my tri-x arial was MUCH worse, putting it from 400 to EI 25 based on tests and expired in the 80's... Crazy... Tri-x can't handle time...

If I can get the bellows on my 116 & 616 replaced I'll buy another 10 rolls of This GAF and respool it, it seems like a good match. that is if you guys don't buy it out from under me lol

What will it take to get you to post that shot again with you in your flight suit? :devil:

Matt;

That shot is in my gallery!

Stone;

I was in the USAF and worked at EK, so I have worked on both ends of the supply chain. Aerial film used by the USAF was procured from either EK or Dupont and came in 5" and 9" rolls. These rolls were exactly like 120 rolls but bigger and the film length was about 90 feet. They were used in aerial cameras, and I have posted a picture of an RF101C that I took while the plane was being serviced. The open bays shows 2 or 3 cameras. They used 36" lenses or about 900 mm. The cameras produced overlapping frames that were read on a special device that produced 3D images.

BTW, your hanging film shows no perfs, but the closeup sample has perfs. Whats up?

I think I need to pay for the privilege of viewing your photo gallery, as I "don't have permission to view this"

You have to look closer, zoom in on the closest strip, the perfs are there I promise

Alright, I have checked the USAF Handbook for Photo Lab Processing (AFM-96-11. In it, it lists films used by the Air Force for all purposes and for aerial use only Kodak and Dupont are listed. GAF is listed for small camera and sheet films. No joy here! Sorry.

Also, it gives the standard developers to be used. All films must fit a narrow gate for time and temperature in these developers.

All must be able to use darkroom or field equipment.

PE

My second thought was maybe Navy or Marines, but looking at the film canasters does not look like any federal contract that I have seen. In 1976 still lisiting the British exposure number?

Stone, it's definitely worth it to subscribe.

 

[Photo Engineer]

Well, it looks as if it is a NATO number.

Yes Stone, subscribe.

I know, but there are so many forums and they all want me to subscribe, I may be decent but I'm not successful in the financial sense... And as mentioned, I just lost my $2,500 digital in the hurricane which is sadly my primary earner :/

I'll subscribe most likely, just deciding which forum is most worth it, this seems to be the best just want to be sure

What I found most annoying and strange is they come in canisters of 15 feet each like standard Kodak 70mm except NOT in load able canisters, but just on spools, and the spools do NOT fit in 70mm canisters so I STILL have to re-spool them as if they were on 100 feet spools, why didn't they at least fit inside standard canisters... Ugh, I'm sure they are some proprietary GAF product but still silly, at least the bigger spools prevented heavy curling...

Maybe the 70mm cartridges and the resp. spools were not as much standardized as we think. Though in that case I would rather expect a simple cardboard hub for any re-spooling re-fill.

 

[Photo Engineer]

The standard camera that we used for 70mm was the Hulcher. It took spools of perfed film. One of those shots on Ektacolor S is also in my gallery.

So now that time has passed, how to I get a scanner holder that will fit 70mm haha, I have the epson v750-m pro

Flat on the glass doesn't work as its out of focus slightly and gives a soft focus look...

If I raise it up on glass (wet scan glass specifically) I get newton rings and can't get it flat...

This image was a joke and a challenge by a friend photographer who wanted me to shoot a macro shot without a macro lens and use expired film so the 1967 GAF 70mm was the natural choice

Oh part of the challenge was no lighting but what was available so this is probably a 15 second exposure in a VERY dark room with one 60 watt center room ceiling bulb and one 40 watt desk bulb haha

Anyone still following this? Someone SOMEWHERE offered me some GAF developing chemical and I never heard if they had found the stash they might have had... I've looked through all my 70mm posts but can't find who said it haha
