Hello all, some advice needed. I am keen to develop some old rolls of K40 super 8 and other now defunct brands (I know the results will only be B/W as K40 had a complicated 13 step process)
I wish to develop using the Caffenol process but I need to know the procedure (I knwo the ingredients are coffe, vitamin c powder, washing powder et al) But I ideally need to follow a step by step process. Anyone had experience and can pass that knowldge in simple terms on???? Thanks in advance

Hi Jerome, I don't appear to have any message from you? May I ask if you could email direct: mark(dot)barton(at)uwe(dot)ac(dot)uk

Many thanks

Resent PM to your email. The article is too large to post.

I didn't believe the question as well until I read the article from Jerome.

The result is amazing. Below 2 pictures are the example.

cheers,

Hi, Jerome. Could you send the article to me too? My email is:

Thank you very much.

Thanks Jerome, that article will be added to my growing knowledge on the subject. Of interest I have just found out that you can use saltwater as a fixer! How cool is that? Cheers

Dear Maurizio: Sent you 2 files. Have fun.

By googling for "caffenol" there are plenty information we get.

One of them is:

http://filmphotographyproject.com/content/2011/01/coffee-break-%E2%80%93-develop-film-home-caffenol

and this is a blog for caffenol:

But I don't think it can develop K40. Can't it?

Thank you so much, Jerome!!!

I understand that original Kodachrome K40 cannot be provcessed nowadays due to the complicated 13 stage processing, that relies on exact timings and temperatures, plus a complex chemical receipe. But K40 can be processed as a low contrast black and white film, which is perfect for my usage as I further explore celluloid and projection whilst studying for my Masters degree. Cheers to all

Mark,

My understanding is that Kodachrome can only be processed as B/W Negative. Not sure if you can turn this into a Positive.

When it comes to the chemical point of view every b/w film that can be developed into a negative should be able to be developed the reversal way. As far as I understood K40 gives acceptable results in b/w negative while the development as a reversal leads to even less contrast and flat results.
For b/w reversal processing you need a developer that is making a strong contrast (like paper developer); I think the Caffenol process is not in this category and therefore not suitable for K40 reversal processing; I'm not sure about K40 negative processing though.
