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 http://www.photobanter.com/images/icons/icon7.gif 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. |
