This is my first attempt at using homemade developer.
This photo was taken with a Yashica 635 on Ilford HP5 120 400 film and developed for 30 minutes in a homebrew of :
12 teaspoons of coffee (Carte Noire),
6 teaspoons of soda crystals,
1 teaspoon of green food colouring (just for the hell of it)
and enough cooled boiled water to make up to a litre
Most of the 12 shots were underexposed, so I guess that means that they were underdeveloped.
But I am pleased that something came out on the film.
This one is probably the clearest because it was taken with a 1/60 exposure, 6 aperture pointing directly at a light!
Something to experiment with for a rainy day.
Well... the met/quin looked all right, nice (rather grey, and big) needles, but the wax stopper of the second part disintegrated (that's the dark stuff); the act/cons had become rock hard, so I took a hammer and solved that problem. Dissolved the lot (as I did before) and filtered.
But did it wòrk? do you ask...
Well, in fact, it most certainly did! See next pic.

Mozilla Development Center is far better than the default media wiki layout for the type of information it contains.
Flock has similar needs. Right now, we are trying to have all the types of documentation in this one wiki. Smarter search will be needed.
The authors of MDC have done an awesome job, particularly with creating relationships between the information. Representing this information is the challenging part, and one I hope gets attention, both for Firefox and Flock.

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.
