I am new to this forum and are based in the Netherlands.
Technique: 100% traditional, no scanning or digital processing; medium
format black and white (Pentax 67II); Preferred film is Ilford FP4+,
developed in Pyrogallol. 40 years of darkroom and still learning

Having experience with FP4+ in Pyrogallol, I am now searching for a
pyrogallol formula which works well with HP5+.
Before me I have an older formula by Patrick Gainer that I would like to
try.
This formula does not imply any water and/or sodium sulphite as a
preserver.
The formula to make 500ml stock solution:
- Pyrogallol 50 gr
- P-aminophenol base 2,5 gr
- Ascorbic Acid 4 gr
(To dissolve heat the TEA to 150 F)
Has anybody experience with this formula?
How should I mix? Instruction is welcomed.
Is the stain proportional to density as it should be?
Risk of uneven development when using a Patterson tank with spirals?
How does HP5+ perform when developed in this formula? Pro's or
contra's?
Thanks,
Jos.
