We are speculating about Fomapan 100R, not any modern B&W film.
We actually don't know how many layers or emulsion this film is made of.
For the record, it's obvious that any modern B&W film will be a combination of different silver halide configurations that vary in speed and spectral sensitivity. Whether it's very useful to distinguish two, specifically, I couldn't say.

It's even much more cheap to use this DIY process by Friedemann Wachsmuth (sorry the website is in German).When you'll able, get the Adox kit: it's as good as the Foma's but at half the cost.
I was thing the same, but processing in also a little more involved with transparency/slides. I have two nice 35mm stereo cameras, viewers and complete Realist slide mounting kit. I just might try my hand at processing a few rolls as B&W slides to see the results. Who knows, I might just like it?
Seems like everytime I look for Adox products, my normal US suppliers never have any. Right now, Freestyle is showing "out of stock" for the Adox reversal kit, and the Scala 50 film, and the CHS 100 II. B&H has some Adox Scala 50 film, but no Adox reversal chemistry.
Normally, I prefer to shoot films which I can expose at EI 100 (or preferably higher). I might be willing to try some Scala 50 if I can get good results metering at ISO 50. However, if it needs more exposure than box speed, I probably won't have enough patience to shoot it.
No time to watch the video today -- I have too much stuff to do in real life right now. So I will have to wait another day to do more research. Thanks for your advice.
Reversal processing is so satisfying!
What kit / process did you use, and what was the 1st Development time/temperature?
The ISO 400 is a gross negligence/poor storytelling on Rollei part. It's a respooled Aerial film with about 100 ISO for pictorial contrast.I developed a roll of Rollei 400 yesterday and it reversed quite nicely. Strongish contrasts, but they look good on the screen

Try it at ~100 or 200, reduce 1st dev time accordingly and enjoy better slides!
Yup. {Moderator's deletion of political comment} "Trust, but verify" doesn't event work today. Just "Verify"remainsAye. I went for the lower figure. Some of what I'd read about it suggested to treat it as having an even lower ISO - down to 50. I no longer trust box speed for any film anyway. I always check for user experience on the web now. The sale of it at 400 does seem a bit excessive, though.
Certainly can be done, but I personally wouldn't go so low with Aviphot 200 derivatives for everyday shooting, but Pull Processing is a thing after all.Aye. I went for the lower figure. Some of what I'd read about it suggested to treat it as having an even lower ISO - down to 50

Yup. I played for 200 in the end. I got a few rolls very cheap and this one was wa sort of in the "test" category. I know. Testing film for something as generally tight as reversal is probably not a great idea, but...
I think testing is just about taking photos with different exposures, cutting it into several sections and developing until a set of usable parameters is found. As the detailed tutorial from Ivo Stunga.
The main issue is that for poorly expired film, the next batch you buy might have spent several summers in a hot garage, causing the required parameters to differ from this one and necessitating a retest.

Nowadays Dokumol/Eukobrom developer can be replaced by Ilford PQ Universal. I have not yet done so but I will sometime - just have to check the correct time for PQ als a first developer.
I have developed about 50 films with it (mostly Fomapan R100, some Rollei Infrared 400 also, still in Dokumol) and it's a pleasure. Costs about 1 US$ per film roll.
Unfortunately, there are new regulations in the EU. making the ingredients for bleach hard to get. Sulfuric acid is almost impossible to buy. Anything 15% or more is prohibited for retail, and chemical companies don´t have 10% available. Also, potassium permanganate is listed as a schedule II narcotics precursor, and buying any quantities more than 5-10 g from a pharmacy will need a lots of paperwork. Even in a pharmacy, you will get strange looks. Maybe they prohibit dihydrogen oxide (H2O) next year, as it has many illegal uses too...
Yes, this regulation thing sucks, especially since it doesn't actually stop those who want to abuse it.
I talked to a household chemicals supplier - he told me that in fact I can get many of the things as a "finished product", but not as chemical reagents. For example, potassium permanganate 100% without impurities can be taken as a disinfectant for seeds and greenhouses. Here in Bulgaria, sulfuric acid cannot be taken as such - regardless of the concentration. If you have access to 10% - it will do the trick. However, here it is not a particular problem to put on some work pants and take a 5 liter can of battery electrolyte - the situation is saved

Just for interest, when was Fomopan R first made?
For the moment I can’t tell although I constantly do research on motion-picture film products. Around 1958, I think. Fotochema made an R 17, an R 21, and an R 24. With the abandonment of the slower as well as the faster emulsion the R 21 was renamed R 100. Or later.
Before being branded R for Reversal, Fotochema had a Fomapan Super 21° DIN film. This I take as a trace to Eastman-Kodak Super-X. It was named Fomapan 21 in the sixties.
Fotokemika’s Fortepan, 80 ASA, seems to have come directly from Rochester. And then you had Fotopan R 50 from Poland. Maybe also American.
