How to use Positive Film as black and white

[mohmad khatab]

You might search for "develop slide as negative" or "develop e6 as B&W" or "develop e4 as B&W"

First, let me apologize if I misinterpret you. I know there is a language barrier.

You have color slide film, and want to develop it as B&W. You do not care if it is positive or negative. A negative is acceptable to you.

If I understand you correctly, what you are asking should not be too difficult for some of our more experienced members. I think many people are simply looking at "color" or "slide" and may be missing a simple solution. I am not good at alternate development, so cannot give good ideas.

I could not find much on this board, only this:

God bless you, my dear brother .
No need to apologize . We are all colleagues and brothers and help each other.
I am very grateful to you.
I will start the experiments and publish the results successively, and I hope that the experiments will be of artistic value.
Greetings to you .

I did reversal processing of expired Kodak Elite Chrome 100 E6 film some time ago. So it's not impossible to make B&W slides from E6 film. I used my own first developer which requires tuning for each film. In your case since you've E6 chemistry, you can perhaps use E6 first developer itself as the first developer in your B&W reversal processing workflow and find out what it gives you. Of course, it is advisable to do this first with a small strip of film.

Yes brother Raghu.
The young man developed this movie using the developer (Kalogen) and did not consult with me about it.
Of course, this is a calogen that does not contain thiocyanates or thiosulfate .. It is a completely ordinary developer used to develop ordinary films. And I don't think he is fit to be a first developer.
I will use the usual (ORWO4185) process.
But after I do one last chemistry experiment (E6) so I can cut my doubts with certainty.

I will use the usual (ORWO4185) process.

Orwo 4185 process was designed specifically for reversal processing of Orwo UN54 film. It might or might not do well on other films as the first developer has quite high amount of Thiocyanate in it. Do your testing with a small strip before you put an entire roll into it.

You know very well that this process worked well for me on Ilford films, I even used it with FP4 with Theoria and it produced a white and brown slide. Even the expired Ukrainian film Svema from the 80s came out with very acceptable results.
What's wrong with you, man?
Uncle ORWO never said that this process was specifically designed for his emulsions only.

Yes, I understand your point, dear brother.
Practically speaking, your point of view is actually correct.
But that's the last detail we're thinking about right now.
Aside from printing, the main issue is, can we get black and white negative or positive film using E6 film?
This is the main goal.
Generally . Tomorrow I will start preparing the rest of the chemistry solutions needed to start the experiments.
And definitely I will tell you about any results I can get.

Brother Mohmad,

I don't understand how these rolls are giving such bad results on E6 or even on C41 processes. Have you tried bringing them to other lab?

Those films should give better images, even despite them being outdated.

If "worked well" means getting some positive image, yes you do get a positive image if you use the Orwo first developer. As I wrote earlier, Orwo first developer works best for Orwo UN54 film. With other films, results can be less than optimal.

Brother Flavio
Brother Raghu
I am now working on experiments.
I will write to you a comprehensive report on those experiences at the end of the experiments so that we can put comprehensive answers to all these questions.
