Kodachrome 120

RoBBo · Aug 29, 2007

Found a little bundle of this on ebay, I was waiting to snatch it up relatively cheap and shoot it like a mad man.
Until I realized there's no place I could get it processed...
Sad day, I was so excited for that...
Must have been beautiful.
Anyways, I thought maybe someone here might be interested in it for some reason other than I was. So here it is.

Did you ask if Dwayne's could process it?

David A. Goldfarb · Aug 29, 2007

They don't. It can only be processed as B&W at this point, unless you're able to set up a K-14 hand line.

One has to wonder why Dwayne's doesn't set up a line to process 120, like, twice a year or something and charge a lot of money for it. They could probably get a few people to pay $25 a roll for the service, which is what salvage processing usually goes for with obsolete processes.

Might be worth a quick call to these guys http://www.duggal.com/01photo.htm to see if they really do still process it, or just haven't updated their web site.

No point, Dwaynes is the only place left on earth that can process Kodachrome and they can't do 120.

Unless you do it by hand. The formulas are published, and it can be done.

I'm pretty ambitious with a lot of things, though unless you want to personally give me a hand...
I think I'll have to pass on that for now.
Maybe next year.

Photo Engineer · Aug 29, 2007

I've seen it done by hand.

Other than the difficulty and expense in getting the couplers and mixing and a long process it isn't too hard.

If you really want it, you will do it.

Hmmm...
Kodachrome in 120
Might be worth it!

Dwaynes is the last Kodak authorized k-14 lab. That doesn't preclude unauthorized labs from doing it. If I'm not mistaken, there is also a Japanese lab that still does k-14.

I'd be very interest to see the formulas - are they somewhere on Kodak's website?

Thanks,

Matt.

They are in the patent. It has been mentioned in this forum several times as has hand processing. I don't have the number handy. I think that one of the threads was titled "Kodachrome secrets".

FYI I checked Rocky Mountain Film Lab, who specialize in discontinued film types, and even they won't do it (except as black & white). They might have more information about someone who does though: http://www.rockymountainfilm.com/k14.htm.

Assuming one was to try to do it themselves, theoretically you could use and older process like K-12, right?

No. That would be like using C-22 for C-41 film or RA for EP-3 paper.

The problem with K-14 isn't so much in the chemical steps: It's in the red and blue re-exposure, which is tightly calibrated.

A few months ago, I updated the K-14 page on Wikipedia, with info gleaned from Kodak Processing Manual Z-50 volume 3.

Craig · Aug 31, 2007

PE,

Do you know how Koadachrome sheet film was reexposed to light? I can see how it could be easily done on a roller transport machine for roll film, but I think it would be much more difficult for sheet film.

From the cleat marks I've seen on Kodachrome sheet film it looks like it was done on hangers just like a dip and dunk E6 line.

Photo Engineer · Aug 31, 2007

We did sheets and strips on hangers and exposed easily with a red light to the back and a blue light to the front. We used wratten filters.

As long as the film is flat there will be no problem. The light should be directed to just one face and perpendicular to the film. It can be moved up and down a length of 35mm but not horizontally or you can get light around the edges.

It isn't that hard. Once you calibrate your light, it works fine. How do you think we processed small batches of experimental coatings, or how did we do small batches of experimental developers. By hand with hangers.
