Hello to everybody - it is my first post here.
Chokeberry a very astringent and tannic taste fruit.
They say it contains a lot of phenolics.
Googling "chokeberry film developer" gave me two inputs:
one and second, producing film developer almost out of everything and ascorbic acid plus baking soda added.
I did sometime ago a chokeberry wine (berries steam distilled, sugar yeasts added and fermented - very dry, tannic, no one wants to drink it - banana wine is a lot better, they say chokeberry wine is best for blending wines).
It is my recipe for chokeberry wine developer (I know it is a hard to reproduce one but it works rather like a conventional developer, so experimenting with the main ingredient is worth a while):
chokeberry wine: 500 ml,
NaOH: 10 g,
KBr: 6g (antifogging agent, might be less when developing not long ago expired films),
temp.: 17-20 degC, (26 degC gave overdeveloped negatives),
time: 15-17 min.
The developer after first development was stored in a refrigerator and after a week it kept its properties.
Negatives are of reddish hue.
I read a thread on apug concerning red wine (grape) developer where one of conclusions was better to consume wine and leave development to well known products but I presume it is not a winemakers or tasters forum.
What are your opinions, would there be a difference in developing properties between a fermented juice (wine) and straight juice (haven't tried it yet).
