This is an experiment combining p-Aminophenol(ates) and Ascorbates (Vit C).
All the experiments are done on PolypanF.
The intention was to use less VitC than the usual formulae.
(reason : Rodinal/R09 1+100 only contains something like 0.6 g/L pAp developer, why use
several grams of VitC, with a high risk of fog and not so fine grain.)
(All the next amounts/weights are for a 250cc developer.)
I used 0.5 g VitC in combination with R09 1+100 1+200 1+250 and 1+500 -- I also used it in
combination with 4, 6 and 9 g instant coffee. (the pictures at the Ursel Castle are made
with the 9g.
I call these developers VitRo 100 .. 500 and VitCa 4,6 or 9.
It has to be noticed (visible with the Rodinal combination) there is no single trace of
oxidation (against the air - the reduction of silver salts works as normal, even stronger).
(Agfa claimed the darkening of the Rodinal during development is a result of the anti-halo
layer, this is only partly correct (simply because films without this layer also show this
result).
The VitRo developers contain :
3 g Soda (deca) .. Na2CO3.10H20 (= 106 + 10x18 g/mol - to calculate the mono etc..)
(this is needed to neutralize the H's from the Ascorbic acid, otherwise it will
take the OH's from the Rodinal/R09 and turn the developer ineffective).
0.5g VitC
2.5 - 2 - 1.25 - 1 cc R09
2.5cc of a 2.5% solution of Borax. (finer, rounder grain)
Example above is made with the VitRo 250.
Developing times : (PolypanF)
VitRo 100 12' 80iso
VitRo 200 20' 64iso
VirRo 250 25' 100-125iso (example above)
* VitRo 500 40' 64iso
(*) to be calculated : enough developer for the silversalts on the film ???
-----------------------
The VitCa is trickier, because the acidity of the coffee.
I start with 4g Soda (deca) and add 0.5 g / g instant coffee.
VitCa 60 = 7g Soda (deca)
VitCa 90 = 8.5 g Soda (deca)
After the water, the soda, the VitC (0.5g) I add 1cc 0.1% solution of KI (Potassium Iodide)
The VitCa 60 shows less contrast than the 90, perfect for portrait ...
Developing times between 50' and 60' push the PPF about 2x in the 90.
The 60 after one hour seems to reach 64iso (but I only tested with studio light, outside light
needs to be tested).
But should make excellent developers, with fine grain and great tonality and the ability
to push the film without burned-out highlights several stops.

This time I did ID-11 weaker diluted in Rodinal 1- something ;o). I think I like this combination. It leaves an even developed scan across the board. It is like split grade printing before I hit the darkroom. :o)
Kentmere 400 film in a Canon AE-1p with 135mm M-42 Mamiya/Sekor lens
Artist....The King of Chalices card suggests that my power today lies in emotional availability. I inspire, protect and nurture with reliable compassion, respect, and affection. I am a master in the art and am secure enough in my role to connect to, express and pursue my hearts desire while defending the greater good of those who rely on me. I am empowered by consistency and patience while trust is my gift or Holy Grail.

Could only find 1 with experimenter using Pyrocat HD on Kentmere film. Looks OK though without a lot of grain. Might need to lower the contrast with agitations.

A developer wants to turn a prime piece of public space into a marina catering to extra big yachts. The premise is that they will bring an economic boost to Victoria but there are loud protests that it will impede safe use of public waterways and spoil the locale for residents and strollers/joggers.
Over 50 canoes and kayaks came out to show opposition among a crowd of over 100. High winds made a planned spatial demonstration impossible but also highlighted the inadequacy of a mere 8m leeway next to taxiing floatplanes.
The overconsuming ultra-rich lifestyle should not be pandered to at the expense of broader public quality of life and global sustainability. If cruise ship passengers aren't scared away from Victoria by docking out at Ogden Point then why should a much smaller number of millionaires get such special treatment? I doubt it will really bring that much more money to the city.

Bluegreen, the developer of Mystic Shores, was formed over thirty-nine years ago with purpose of helping individuals and families find rural vacation land and homes. Bluegreen was early to recognize the desire of many city-dwellers to have a haven from the stresses of urban life, and has made it their goal to create more than just a successful corporation... we create communities where people can relax, where families can return to a simpler and safer lifestyle we recall from our childhoods.
