20yo C41 in Rodinal?

[John51]

fwir, 1:100 Rodinal stand developed for one hour is a one size fits all and suitable for that old film that came with an old camera.

I'm assuming that means b+w old film. What I have is an exposed C41 400 asa film that was in a Praktica I was gifted. Guy hadn't used it in 20 years or so. I'd like to process it for him as a thank you.

1:100 stand/semi stand for an hour or some other dilution and time?

If Rodinal is not that suited to cross processing, I also have HC-110 and the chems to make D23 and DD23 2 bath.

What will give me the best chance of getting images from this film?

A few months ago, I developed a roll of Kodak BWC 400 from 2003 with HC-110 dilution B 5:30min. The negative looked a bit dark but I got nice scans.

Developing it in C41 chemistry instead of Rodinal.

You have a point but I'm not going to do that. As the guy has forgotten that there was film in the camera, nbd if it doesn't work. Will be a test in case more old film turns up...

...like just now. The Kodak Signet 35 I bought from the US has just been delivered. Had film loaded and the counter showed 30 exposures. Rewound it and low and behold, Kodachrome 64.

If you insist on using B&W chemistry, you may want to see this discussion and in particular post #3: https://www.photrio.com/forum/threads/developing-c-41-color-film-w-d-76-b-w-chemicals.156712/

I’ve had very good results using 20-year-old color print (C41) film and developing in Rodinal 1+50 for 15 minutes at 68F.

That said, film that is 20 years old and recently exposed will likely behave differently than film that was exposed 20 years ago so a clip test might be advisable.

It’s unlikely you’ll be able to use that Kodachrome with this method. Whole different animal there.
