Stand Developing C41 film in B&W chemistry

This is a very interesting thread, and an interesting technique. I've been reluctant to use colour film for some time now, due to the absence of local processing outlets.

I wonder, though, whether the film, once developed in B&W process, can thereafter be reprocessed in colour? I seem to recall some such discussion, from years ago.

There is, somewhere, a Kodak report on how to do it.

After developing as black and white, you have to convert the developed silver back to bromide, then ordinary color development will work.

You will still have the orange mask, though, so it isn't easy to print the black and white negative.

I think that was in the days when Panalure was still in production, in which case you use that.

Also, it should have the right contrast to go with the low gamma of such films.

This is from a roll of VR1000 that I developed in, I believe, HC-110.

It had been stored less than optimally, especially for a high-speed film.

There is a lot of fog, either due to poor storage or overdevelopment, as I didn't really

know how long to give it. If you look at the negatives, they almost look all black,

until you look closer. You don't see the orange mask.

Next time I have some to do, I might try stand. But mostly I try to use not so old

film, and real C41 processing.

I'm just adding a few more shots, using the same template as the previous set except these were from a cassette of about 20 year OOD Kodak Gold. You can see how the image quality has degraded and shows a lot more grain compared to the In Date Agfa Vista submitted above, but still quite usable for my camera testing purposes. This time shot on a vintage Pentax MV … so fully automatic aperture priority exposure.

Old thread.

What is the information on Ilford 3 and stand development times for the Kodacolor and Ektacolor. Thanks

No idea for Ilfosol, but if I am not mistaken, not a developer particularly suited to stand development.

Since I used to have a pile of expired C41 film, I used to use Rodinal 1:100 with stand development for 1 hour for test shots. It rendered grainier results than the OP has posted, but for testing purposes good enough to understand if a camera is working correctly. Rodinal is cheap enough and has pretty much infinite shelf-life, so useful to keep around for purposes like this one.

Personally, if I had quality films (Ektacolor for sure), I wouldn't go down this road, but rather just get them properly developed.
