Kodachrome 25 - a few quick questions

[2F/2F]

Hello,

I have a roll of double 8 K25, expired 1979 that came in the case with my Nizo S2R. I am going to shoot it for the heck of it.

1. Was *all* Kodachrome 25 made for process K-14? In other words, could this possibly be a K-12 film?

2. Do you expect I will get anything at all from it? It has not been refrigerated, and was still factory sealed.

3. Is there anything I can do (such as over or under exposing, altering development, filtering, etc.) that will make it more likely for me to get anything from it?

4. There was also an exposed roll in the camera. The leader is punched "K[dot]1 0-6551 70503". The spool (light grey plastic) has "R-140" molded on side 1. Any idea what emulsion this is? The unused roll of K25 is punched "KM [large round hole] 0-674431 704". The spool is stamped the same as the other one, but is black instead of light grey.

If anyone wants the box and/or instruction insert, you can have them. Otherwise, they go with Tuesday's recycling.

Thank you

-No all Kodachrome 25 was not K-14. It should say K-12 or K-14 somewhere.
-You can cerainly expect some image on the film. I am guessing it will have an extreme magenta shift, but there is no way to know until you shoot it. When did it expire?
-That is probably not a K-14 process....Dwayne's can tell you for sure.

"It should say K-12 or K-14 somewhere."

It does not; hence the question. You will see this when I send you the box. I though it was kind of weird myself. I may be blind, though I looked three times.

"When did it expire?"

1979 (mentioned in the first sentence of my post!)

This is actual "Kodachrome 25", not just a Kodachrome type that is ISO 25, like some earlier Kodachromes that were not named "Kodachrome 25", such as Kodachrome II.

 

[Ektagraphic]

Sorry...Just got up ...I believe that the K-14 process began in 1974....

K25 is always K14 process, the name changed from Kodachrome II when the process changed. Chances are the film will have aged badly but it might be worth a try if the processing was included.

I've got some Kodachrome 25 that is a mere youngster compared to yours, having expired, I think, in 1989. (luckily, properly stored in a freezer its entire life) If my results are any indication, you can expect a noticeable magenta shift in the whites of clouds and other tones, but you may still get some nice greens and blues (and of course, reds). The magenta is more noticeable when shot at box speed and dissipates somewhat when I over expose by a stop.

One option, (which I wish I had taken with my one and only roll of EIR :rolleyes: ) would be to re-spool it down to two or three shorter rolls so that you can make adjustments based on your results.

Good luck, and let us know how things work out for you.

Cheers,

If a magenta shift is expected why not use a light green filter on the lens?

I thought about it, and I decided that I was more curious to see just how it comes out if shot and processed as if it was fresh. I was not really interested in getting usable footage from the roll. I found out that it was K-14, so I shot it to process in color, and we'll see what happens when I get it back from Dwayne's!

 

[nickandre]

It is all K14. The only K12 emulsions were KII and KX. You'll get a bad magenta shift. Assume it has bad speed loss and base fog. You will probably get very magenta images if you compensate for speed loss. It's just a B+W film after all. Theoretically if you recalibrated the K14 process, you could get correct color images from the film which had a reduced DMax.

I shot a roll of S8 kodachrome from 1979, there were definitly images, but some were very faint. A few scenes came out pretty good, but it all had a terrible magenta cast. Shoot it!

I found this on flikr. They are from 73, 79 and 83, you can see the aging differences.

Camera neglect, guilty as charged! About a month ago I pull out my Nikon and found a roll of K-25 still inside, 22 of 36 exposed. Curious, I sent it to Dwayne's, this is what looked like:

The image is a show opening 10-years ago. Dwayne's was nice enough to send a note describing how badly I screwed up "...improper storage, expired film," etc, etc...

I really wish a place like wittner would roll up Kodachrome 64 in super 8 and double 8. Wittner still offers K40, but...it is a whopping $40! That is a bit too much for me to use the film more than once.

 

[nickandre]

I splurged and bought one roll. That brings my count up to 2 rolls of K40T in the freezer.

I was also thinking the same thing but I don't think you can buy K64 in those lengths and it would be HELL trying to expose that in most super8 cameras that have "kodachrome" or "old ektachrome" settings on them.

 

[nickstreme]

How do you order it from wittner? I dont speaka any german

 

[Ektagraphic]

Google will convert the page over for you. Why would Kodachorme 64 be hell? I use Ektachrome 64T all the time.

I think he's referring to the fact that many cheaper S8 cameras can only read K40 and E160, and nothing in between. Most decent cameras can read other film speeds so it isn't an issue.

I had some Kodachrome 64 with a 1986 expiry date on it. One roll had already been exposed by its original owner (I assume around 1986) so I used the other two and sent all three off for processing.

The two I recently exposed came back fine but with just a slight cool tone. The roll shot twenty years ago had images but they were dark but still colourful, unlike the sample image posted by Iwagoshi (above).

So I think it is worth trying it out. Nothing to lose really.
