I develope the Technical Pan in a Pyro Modification I call PPK
(Pyro-Phenidon-Kodalk)that I mixed first when I had to develope some rolls
of 135-TP with Insect-micro studies.
The negatives show good shadow details and useable contrast - I printed on
grade 2-3 in VC fibre where I got stunning results in sharpness and
tonality - really good pyro negs.
If somebody wantīs try it I give here the recepture:
Leban PPK-Developer
a Pyro/Phenidione/Kodalk developer for Kodak Technical Pan
Part A:
5g Phenidone*
2g Sodiumbisulfite
5g Pyrogallic acid
0,5g EDTA-Na4
dissolved in 100ml distilled water
*This makes only a suspension because the Phenidone donīt solves completely
Part B
is equal to Part B of PMK (300g Sodium metaborat in 1l distilled water)
Working solution
5ml Part A (you have to shake it to get a homogene suspension)
10ml Part B
in 1l water
Developing process:
Technical Pan exposed with EI 50
dev.Temp.: 22°C
dev. Time: 6,5 min
I did it in a tank by hand and 1min shakes:
I used no prewetting, and normal fixing
and a after bath in Water + kodalk.
I made no physical tests with my negs - I only printed them and was happy (
means I have no curves, gammas,etc...)
Good luck
