As the Fomapan R100 SW transparency has unfortunately been out of stock for quite some time, I am looking for a replacement until this film becomes available again. In the meantime, I have conducted exposures with MACO Po 100c and Agfa Scala, and had both types of film developed as transparencies at Dormoolen in Hamburg.
However, as I like to develop my own film, I am looking for an alternative – specifically one where I don’t have to carry out lengthy test runs and experiments until I get the right result.
FOTOIMPEX offers two reversal kits (Foma and Kodak), as well as a wide range of films with clear base. Has anyone tested either of these two reversal kits with films other than those intended for them, and can they provide the initial development times and the speed achieved by the films?

I’d just like to point out here that we can supply sufficient quantities of Fomapan R by the metre.
Otherwise, please see my reply in the parallel thread.

Hello Christoph
There’s one point I haven’t quite grasped:
what’s actually wrong with developing
Agfa Scala and PO100c yourself?
I’ve been processing PO100c for a year and a half now,
sometimes using chemicals I’ve mixed myself.
The primary developer is Neutol NE 1+7 with potassium iodide
and potassium rhodanide additives.
I’ve also tested the Foma R100 with it.
PO100c is running out.
Will Scala still be available now that Agfa has gone bust?
What about Neutol in the future?
I’m currently assuming that
the Fomapan R100 will be the material available for the longest
term, so I’m focusing
on that now.
Perhaps I should simply switch to Fomadon LQR
as my primary and secondary developer, if
the Neutol runs out?
Good light

Hi Dennis,
What development times, agitation frequency and how much potassium iodide
and potassium rhodanide do you use?
And is the PO100c running out?
I’m going to try developing an Agfa Scala in a Foma kit. I’ve heard that you can get 125 ASA with the standard development time of 12 minutes. Just give it a go.
Best regards
Christoph

Hi Christoph,
Just type “kehret um sw-magazin” into Google. The results will show a link in the two-line preview; paste that into your browser and then click on something similar to that :-)
Michael and Roman have kindly given this a go and made their findings available to everyone.
I didn’t want to give the direct link, as it points to one of Mirko’s competitors. And if I’m not mistaken, that was already mentioned in the parallel thread. But I’m not entirely sure and too lazy to check right now.
Best regards,

Hi Christoph,
I’ve still got 10 rolls of Fomapan R100 135-36 – expiring sometime in 2006 – which were sent to me by mistake; I never got round to sending them back to Impex. You can buy them off me. Can I find your email address here somewhere? Then we can sort out the details offline.
Best regards,

Hello Christoph!
So, PO100c for slides
My initial developer
Neutol NE 1+7
50 mg KI per litre of working solution
5 g KSCN per litre of working solution
Jobo 1540 canister with 4 films and 1 litre of chemical solution
20.0 degrees Celsius (possibly in a water bath)
Continuous agitation for the first minute
then agitate twice every full minute
Initial development total 11 minutes
In the Czech Plastimat canister
the initial development time was shorter
(more like 9 mins)
Stop bath: citric acid 1 teaspoon per litre
Bleaching in KMNO4 + H2SO4
Clearing: 9% Na₂SO₃
Second exposure
Second developer: Neutol NE 1+7
Stop
Fix
Rinsing ‘Ilford style’ with tempered H₂O
In southern farms, EXCEPT for developers
and Bleach bath, I use Hüter LP Geladur
with a dilution of 1+500.
Keep everything running nicely at 20 degrees, otherwise you’ll
still lose the emulsion on the film in no time :(
I mix everything from a
bucket of water kept at 20°.
The result is quite soft B&W slides with
crystal-clear highlights and rich shadows, shadows that
(measured with a handheld meter against black pieces of film
against a grey sky) are about four times
(-2EV) more dense than the blackest blacks
of E100VS colour slides from the professional lab.
It is precisely this ‘dynamic range’ that
really appeals to me about the B&W slides.
I then specifically look for subjects that suit this:
backlit situations in bright sunshine,
sparkling water surfaces, light sources in the frame...
There’s plenty of information in the aforementioned
“Kehret Um” thread in the neighbouring forum.
That was the “spark” that got me to
give B&W slides a go too :)
Well then, have fun
Dennis
