Kodak Aerial double X

[haryanto]

Hello there,

I have a few roll of Kodak Aerial double X 2405, cut into 4x5, for this 1-2 years I used it with normal development Pyrocat HD, 1:1:100homebrew EI 250, with normal result, but suddenly in this week when I try to develop several negatives of kodak 2405 the results is heavy foggedall surface been develop, for the first time I suspect problem came from developer, but I test the developer with Kodak Tmax400, normal, any suggestion what happened?

nb: I tested too with several developer in normal strength had same results, I use benzotriazole 10-20ml per 300ml working solutions PHD got thin negative and have to reduce iso to 6

How are the cut sheets stored? Meaning particularly the ones you had problems with, of course.

 

[haryanto]

I stored in freezer in tmax box , even the rol that i'm not cut, tested and fogged

You might have better luck with sheets in the center of the stack, and film a few wraps more inward on the roll. ISO 6 is a huge drop in speed even with a restrainer. Maybe try a more active commercial developer such as hc110 dil b which will develop it fast and hopefully keep a bit of the fog from developing out. Good luck

 

[haryanto]

Thank you Newt, I tested every box randomly from the bottom, middle and etc, exactly the same result, I tested with various developer

 

[Mark Crabtree]

Really odd. How fogged? Can you post one the has been shot then processed. A picture of the full negative on a light table or something of the sort will help show the problem.

How old is this stuff? I have some Plus-x aero that is quite old and still great, but have had Tri-X aero that showed a good bit of fog.

Oh, I see you are using pyro. It would be well worth trying some standard developer. HC110 is about tops for outdated and fogged film.

 

[haryanto]

Yes Mark I've tried several developer like rodinal, d76, and few others, still got the same
a month ago still got normal result.

have you had any chemicals in the fridge or even in the same room as the fridge?

 

[Newt_on_Swings]

Have you tried a blank sheet straight into developer stop and fix? Possibly your camera setup is at fault? Such as bellows going? I was reading a thread here or lff about replacement bellows from overseas not being able to pass a flashlight test due to a change of materials from supplier that the manufacturer didn't even know about. Did you get new bellows installed? Or check existing one for pinholes?

But that doesn't explain the fogged edges. If it was a light leak in the camera, the edges would still be clear.

Is the development in a tank system of some sort, perhaps with a new crack or a missing light baffle?

If tray developed, are they done in a place that has - for example - a new electrical device with a pilot-lamp (an led that flicks on for a few seconds etc.)?

Using several developers to see a similar result on the "suspect" film, while using the "suspect" developer with other films (using the same developing method?) and not finding a problem, does suggest that there is a film problem, but ordinarily fogging from age is very gradual so an environmental problem of some sort seems a likely culprit.

 

[haryanto]

I've test the setup (camera, chemical, darkroom etc) with tmax 400, and got normal result

Such a mystery, did you bring home anything highly radio active? That's the only other thing I can guess besides some gremlins sneaking a peak at your film stash in dim light.

 

[haryanto]

Offcourse not Newt lol, but somewhere here I read Photo Engineer wrote about cosmic ray and effects to age of film and paper, this year sun storm very highly active to disturb sattelites communication, dunno

This pic I take serveral months ago with the Kodak Double X 2405, very beautiful film,

 

[Mark Crabtree]

This one is baffling. I don't think you ever said how old the film is.

Expiration date?

I've never heard of film going off so suddenly without a reason (heat, etc). I understand sepia tone fumes can cause fog, but can't imagine that making its way into your package film in the freezer. There must be some cause. Radon, cosmic rays. If this is very old film, maybe it is right on the edge and doesn't need much to push it into fog. I don't really believe that, but it is a possibility.

 

[haryanto]

the expired 2012 and 2010, I've heard that 10-15 years old still got good result.
This film is sensitive red,
I still hope that I can still use it, still try to find the cause.

Thanks

 

[Mark Crabtree]

Wow. That's not old at all to me. I've got some aerial film from the early 90's. Maybe 80's. Not the same emulsion, but that really doesn't seem plausible.

 

[analoguey]

Maybe check your developing notes/process to verify no changes occurred?

Very beautiful indeed. Maybe give it another shot with some KBr instead with various concentrations. Just cut a sheet into multiple pieces and have it go straight into developer and fix it. Once you get to a concentration where the base fog is acceptable try it again with an exposed image adding more exposure progressively.

 

[haryanto]

I did, got EI 6 or lower, fog decrease significant with benzotriazole 1% 20ml
Thanks

Man, I don't know what to say then, that's as slow as lith film. Might only be useful for experimenting or in alternative processing such as photograms or solargrams or contact dupes.
