How to expose Kodachrome 40?

zowno · Sep 20, 2018

I just got my little hands on a roll of kodachrome 40 in 110 format. Expired in 1976 and I'll be damned if it was ever in a fridge.
This is going to produce some messed up results colour-wise.

What ISO should I rate it at?

Before we get to ISO, how do you plan to process it.

Theo Sulphate · Sep 20, 2018

Maybe 10 ISO, but you've got a bigger problem: nobody processes Kodachrome in color. Nobody. Your last chance was in 2010.

Best you can do is have it processed in B&W.

No idea! I picked it up from a random market stall. Just assumed it was e6

I see you are in Melbourne/AUS.
No, Kodachrome is definitely not an E6 film.
You might want to make contact with Stephen Frizza at Rewind Lab in Sydney. He recently posted here he was looking for Kodachrome to experiment with in terms of processing. He has in the past detailed at length processing methodologies for Kodachrome and even offered to process it, but amazingly there were no takers, even for around $230 a roll, processed.

I think it could be rated around EI6 to EI10.

Not E6, but K14. Only Kodak or other labs with a K-lab machine (about as long as a bus) were capable of processing that film. So, this isn't something you could hope to do at home; you'd have a better chance of making an atomic bomb instead.

There is one person, possibly two, that has successfully processed Kodachrome beyond 2010 - but it required extensive knowledge and equipment.

...

I wasn't aware of his offer - I have a roll of 8mm K II from 1978 that I would like processed ... I have yet to send it to Film Rescue for B&W processing. I would risk $230 on the chance to get it processed in color.

$230! My god. This is 110 film not super 8 by the way

You nailed the real question, how are you going to get it developed?

I cannot find Stephen's recent post about his request for Kodachrome rolls. I'm sure he did post something.

Could be more. Could be less. My memory is guiding me on what he brought up some years ago.
Processing is and will remain the bigger and more pointy issue of things.
It is a reflection of the time, cost and complexity of the work. I wouldn't think a discount would apply for 110 (and I have never seen Kodachrome in 110 format), but you never know...

Question for others out there: Is there another member here on Photrio who processed Kodachrome and achieved credible results in colour??

Most educational indeed.
And most unlike the colour of Kodachrome I and others would remember, but still, it's better than nothing I reckon!

If PE is hanging around, what is 'reverse engineering' of the K-14 process??

Theo Sulphate · Sep 21, 2018

Good question. I don't think K-14 needs to be "reverse engineered" because the steps are well known and have been published in books and on the internet. Even the chemicals are known. Creating them, mixing, going through the steps are where "the Devil is in the details".

So anyway, those who have Kodachrome today, either unexposed or exposed-but-undeveloped, what they have is essentially a little memento of past history - no more, no less.

He had got some problems with secondary expositions, there are some comments in other images at his flickr.
