we have a timetable on our website for Fomapan films.
Rodinal is slightly higher concentrated as R09.
R09 from Foma is actually made by Foma and R09 from Calbe made by Calbe.
The recipees where made available to all firms in the former eastern block by their system of knowledge transfer and process organisation.
We usually suggest to transfer Rodinal times to R09 times or vice versa by using the 1+50 diluton of Rodinal together with the 1+40 time of R09.
Personally I would suggest A49 1+2 for Fomapan 100.
It gives less grain yet effective 100 ASA speed.
Thank you Mirko, but I have already developed the film. I used Fomadon R09 at 1+40.. I cut the time down to 6 min. to control high subject contrast . This seems to have worked, but I'm reseerving judgement until I've done a few prints.
I am not really interested in a fine grain effect. I like grain!
This question is for Mirko if he is listening, or for anyone else who might know the answer.
My understanding is that Efke films are made in Croatia. Where is Fomapan 100 made? Is it also made in Croatia? Or is FOMOPAN ithe same film as FORTEPAN, made in Hungary?
Fortepan 200 and 400 = Classic 200 and 400. I do not know where Fomapan is made but it is certainly not the same as Fortepan/Classic.
Fomapan is made by Foma in the Czech Republic. It is not a rebranded film.
