Colour slide film in B&W chemistry?

kavandje · Jul 27, 2008

So, I was wondering if anyone has tried this.

I have a roll of perfectly ordinary slide film (Kodak Ektachrome) which I exposed a long time ago, and never got round to having processed. Part of me wants to chuck it in the soup next time I process some b&w film.
Hooopy effects, or unmitigated bleurgh disaster? Other suggestions (other than "take it to get processed")?

This is a question that is quite often asked. You will get a very foggy, yellow negative image which will be difficult to print. You can scan it easily and correct for the yellow cast and fog, but that is not a topic for APUG.

If you process in reversal B&W you will get a positive with low dmax but without the yellow color.

Yep, that's about it. I tried it once just for grins. The resulting negatives are darn near impossible to print conventionally. I didn't bother attempting a scan.

When I was in school, this would happen when students had to shoot a 4x5 black and white negative and a transparency. The film boxes got mixed up fairly frequently (particularly with photographers not used to feeling for notch codes). I've never seen a successful print from such a negative though.
