The Adox kit has a capacity of approx. 8 rolls, depending on how big is the developing tank.
It's about plus 10€ comparing to the Foma's one.
The Foma's kit has the same capacity.

You certainly can. But the bleach times will need to be increased (towards the end substantually). Recent testing here at ADOX show that you can actually open the tank to inspect on this. However this information is Beta and not yet official. If you do this the capacity can more than double but we cannot publish constant and easy to follow bleach times like this. The first/second developer has this capacity for sure.

Thank-you, miha from Slovenia - and all of you, indeed;

since over here in Germany there is hardly a lab to process b&w-slide-film - reversal processing. - Thus I also bought them two kits: The Adox and the Foma kit about two years ago - however - did not dare to go on it, yet.

I may expose several film of each trade mark and want to develop them films in a row - in order to adjust the process within days.

As this thread is very long indeed I have to read it over again inf full detail.

I admit that I have not yet checked out the Adox Scala Kit (sorry to say, I will do it in future) - but if it should work with a permanganate bleach bath you might be able to set up additional bath by yourself.
There is a receipt here (sorry that it's in German - deepl might help if necessary) which I have used for more than a year now with good results.
I use a rotating Jobo 510 tank for 1 film with a bit more than 200 ml liquid. Those 200 ml can bleach 3 films 135/36 which I develop during one day.

You are welcome. Just go ahead and follow the instructions precisely. Make sure to prepare everything in advance. You'll need four jugs, mark them so you don't mix them up during the process, and one larger jug with warm water. Foma's instructions suggest several 2-minute washing steps, but I've been using the Ilford washing method instead. Be sure to finish the process with Photo Flo or a similar agent.

For information: did it happen to you to see some sediment floating into the developer bottle of the Adox kit?

Thankyou very much; miha from Slovenia; - and also Alessandro for your advice!! - Coming days I will be off to Lago di Como in the very North of Itaöly again, where I have no aquipment to develop b&w slide's film. I will try here at Lake Constance in December or January.

Thanks a lot indeed for encouraging me!!

According to MSDS paper the composition of Bellini first dev closely resembles D-19. That makes it the most highly buffered developer of all reversal kits on the market. So theoretically it can give you a linear density growth for almost any film stock possible, it will be just a matter of a development time. So I would start with it. And don't trust chemical fogging bath much, they don't store well.

It's possibly mixed as per D-19 recipe because once mr. Bellini told me they uses Kodak formulas exclusively.

E100 is capable of sharp results, even very sharp results with excellent (modern design) lenses
Are you aware what the difference might be in 70's design Vs "modern"?
Because my Zuiko lenses can record very sharp and detailed images on every other film out there that's capable to withstand 50x projection magnification at a short viewing distance.

Considering the proven quality and capabilities of Zuiko - why would E100 be sharper through a "modern lens"?

It's getting quite hard in EU countries to do BW reversal, except with the official kits. The problem is the bleach. Sulfuric acid is banned in concentrations more than 10% for consumers, it is considered a precursor for explosives, Diluted H2SO4 is not sold anywhere. Potassium dichromate is totally banned, and the alternative, potassium permanganate is listed as 2nd schedule narcotics precursor, and is subject to controls. Yes, there are kits available, but as always, they are very small and expensive. For instance, one Foma kit has the capacity of developing 8 rolls of 135-36 film. Not bad, but for cinema film it is a joke. It is one 30, roll of 16 mm film, and costs about 50€,

I don't now about other EU countries, but in Germany we can buy 10% concentration from Fototechnik Suvatlar without problems at reasonable prices.

same with Potassium Permanganate.

I used to buy it through my local pharmacy before that. also no problems but I had to fill in a form about the intended use and prices were a bit higher.

I may suggest you to buy the Foma kit directly from Foma Bohemia, it will cost way below 50€.

Because I am very interested in the answer to the question in the title of this thread, I just read through all 177 posts a second time to see if there was any consensus.
:-(

The Foma kit and the Adox Scala kit, each got about 4 or 5 recommendations. But most of those recommendations were dependent on using Foma R100 film with the Foma kit and using Adox Scala 50 (or 160 if you have some) with the Adox kit. Sometimes the recommendations were ambiguous, so it was hard to tally the results. There was one recommendation for "All of the Above," and one for "None of the Above" -- both by the same person. ;-)

I did not see any recommendations for the Bellini kit.

And there were 5 or 6 recommendations for "Other" -- that is, the Ilford method, or some variation of a diy process not from a kit. (I call this the Luke 11:11 reply, "What father among you, if his son asks for a fish, will instead of a fish give him a serpent?")

Fortunately, the OP was able to make a decision, and was satisfied with the result (see posts #147-161).

for "other", I assume people are using what I use, use a home mixed kit from raw chems. A lot of people dont like to mix their own chems because they are worried about the raw ingredients being toxic. by mixing it myself, I have an always available solution, just have to mix up the one time use amounts for the batch I developing. after using a few of the kits and mixing my own, I settled on a pot dichromate bleach. I take a lot of care when mixing. the results are better than any other solution I tried.

When I get a minute, I'd like to start a new thread:
"DIY black & white reversal: What formula do you use, and where do you get your chemicals?"
Please mention your location up front, because availibilty and sources are going to vary by country.

If someone else wants start such a thread, that would be great, but right now, I've got to get back to work doing boring, non-photography stuff.
