for those of you who are not tired to try a new and really interesting developer.....
Itīs a simple advanced formula that Iīve created with respect to the famous developers of Willy Beutler (Neofin).
I use a fairly new additive to that kind of chemism : Ammoniumthiocyanate - as a stabilizer that keeps the working solution free from aerial oxidation and opens new possibilities to staining pyro up to stand-developing processes.
In fact this pyro formula does have no negative aerial staining, maximum film speed (Acros reaches up to 400 ISO) and a great potential in sharpness and contrast compensation.
Working procedure is the same like in other staining developers: a slightly alcaline pre - and after-bath seems necessary.
There is one formula for 35mm films up to ULF, tray-, tank-, rotation- processing or stand-developing (best results in tank and stand-processing)
For LF users it could be helpful to use the working solution No.II - that brings enough density for alternative printing, too.
Maybe this is only of interest for a handful of "Pyronthusiasts" but worth a try....
I also got amazing results on Efke IR820/Aura - maximum speed 200 ISO through 695nm filter
allthebest
