Lemming
Hello everyone,
I’m new to the forum and would like to introduce myself briefly:
I’m from Munich, I’m 38 years old and, after a break of about 20 years, I started developing my own film photos again about three months ago. As the results were quite satisfactory right from the start (it’s probably like riding a bike – you never forget how), I’d now like to have a go at reverse processing.
First of all, I’ve read all the threads on this topic here in the forum.
However, a few questions remain:
1. Disposal of chemicals:
Collect the developer and fixer as usual and take them to the recycling centre. That’s clear!
But what about the Bleach bath and stop bath?
In the article ‘Kehret um’, which is often cited here, it says that you can neutralise the Bleach bath using soda and then pour it down the drain.
What do you think of that and how do you go about it?
What about the stop bath?
2. E6 stabiliser solution? (Also from the article “Kehret um”)
What is it? When should it be added? Which product? Disposal?
3. Intermediate exposure seems to be a complex topic.
I’ll start my first attempts with a 40W halogen lamp at 2x3 minutes.
Any suggestions for improvement?
4. As I will be working with the Foma kit, the final question is:
should I start with Agfa Scala or Foma R 100?
What would you recommend for a beginner in this field?
Many thanks for your replies!
Regards
Leming

Hi Lemming,
On disposal: When it comes to the Bleach bath, I completely agree with Roman and Michael. With the fixing bath, it depends: If there are only traces of silver dissolved in it -> down the drain. If half the film emulsion is floating around in it: hazardous waste.
In addition, in many local authorities, the following still applies for small quantities: Developer -> down the drain. And as for how to recycle fixer at home in the simplest way possible, you’ll find references to in-depth discussions in the parallel forum in Stefan’s link collection at www.stefanheymann.de.
Best regards,

Hello,
Right, the first four rolls of film are developed!
Two Agfa Scala and two Forma R.
The Scalas turned out well. I was actually quite surprised that they worked out so well straight away.
But the Formas were a complete disaster. The highlights are completely blown out and have a brownish tinge.
Why? I developed both the Agfas and the Formas in exactly the same way.
Does anyone have any advice?
Regards
Josef

Hi Josef,
Could it be that the potassium permanganate didn’t dissolve properly?
That would mean the exposed silver wasn’t bleached out properly, which is why this solarisation effect occurs during the second exposure... (or something like that...).
Strange that it worked with the SCALAs...
Best regards,
Henning

Thanks, Henning, for your quick reply.
Yes, I’d already thought of using potassium permanganate, but how do you dissolve it? Pour it into the Bleach bath and stir it a few times – what else can you do?

Josef: Is the potassium permanganate coarse or fine-grained? I suppose you can only tell if everything has dissolved – i.e. if there are no particles settling at the bottom – by looking down into a transparent container (glass) once you’ve stopped swirling it.
