Hello
I got a batch of expired ( I mean ancient, not only few months old, these have years on their shoulders) mediumformat colour slide film. I want to experiment with them a little and am thinkig on developing them in black and white negative developer. Does anyone have any recommendations or experiences to share on this kind of work? All help is greatly appreciated.

Re: Developing colourslidefilm in b&w film developer
For reasons too tedious and boring to describe, just throw it away. It won't make satisfactory B&W negatives.harmanvalo wrote:Hello

Don't listen to them; I've wondered this myself and have been meaning to do experiments with it (kinda like putting crappy negatives into a microwave - they turn into awesome negatives......) I've seen kids who have no idea what they're doing shoot color film by accident, and then try to develop it in BW chemicals in my school's lab. THe results aren't too interesting, but if you want to try it, go ahead. SOMETHING DOES HAPPEN, it's just nearly impossible to predict until you actually give it a shot. Actually, this was color neg film, not slide...
I think you should try anyways.

Thank you for your replies. I am not trying to make perfect negatives out of these films, for that I have real b&w film, but to experiment with them, some ideas on development times short, long or very long?, and perhaps other things to consider...they might come out really bad or really crazy, the saddest thing is if nothing happens.
Slide film has color couplers in it. These will produce a sort of grey opalescentce on the film. Trust me, you won't get anything useful from this.harmanvalo wrote:Thank you for your replies.

When I saw your question it made me think "I'm sure I've seen something on that subject" After a bit of a rummage through my photo books I found a reference in Richard Platt's "Photo Data"
He says that a colour film processed in mono chemistry should produce a useable image. It will be stained yellow or orange but it should print OK as mono.
He also claims that it may be possible to recover a colour image by a process of bleaching and processing as C41. I can post the full procedure if anyone is interested.

Hello!
I developed an Ektachrome 400 film in Rodinal 1+25 as a test. This film is really old ( expired in 1983 ). Exposing it generously I got extremely dense looking green tinted B&W negatives, which I haven't tried to print yet. But there are real pictures on the film. Anyway now I have somewhere to go from here...one subject one film and bracketing heavily Perhaps I can glean out something out of this batch of 15 rolls of old slide film...

I'm glad you got something out of it!http://www.fotohuisrovo.nl/documentatie/F_pan_R_en.pdf
That's the way to develop a B&W reversal film.
If you have a B&W reversal film, e.g. Scala on normal negative developer processing (e.g. Rodinal 1+25) you will get a rather normal negative.
Scala has a clear base and high resolution especially for reverse processing. Scala also works in the Foma R100 reverse processing developer kit.

something that might work pretty well

Looks interesting, C-41 lab around here isnt cooperative in proscesing my film....but I'm going back home in a few weeks for winter break and I'm sure my old job will do it for me.
