“Bromide drag”, disturbance of stand dev:

My experience so far, including that of a set of friends, is that pure stand development works for most types of film, almost always with good results. In my eyes this is the most foolproof development technique. Use Rodinal and you’re “safe” from almost ridiculously many kinds of mistakes during shooting.
The basics still aplies though; Most important:
a) Keep temperature at the same level all through the dev. process.
b) Keeping things clean is also essential as you’re using a VERY diluted developer (even a very small contamination affects!).
c) It may also be so that the chemistry of your tap water will affect this; e.g. hard, calcuim rich or highly chlorinated may all tilt the results a good deal.
There are wording around on the net about keeping the amount of e.g. Rodinal above a certain level – 4 to 5cc per film if I remember correclty.
I have occasionally used just 4 cc per film (4 cc as part of 400 cc – i.e. 1:100) without problems, I have not tried every film type with that though. No bad results from these for me, yet – been at it for 6 months.
Caffenol has a tendency to not develop the transparent areas of the negative to the same extent as other developers. As you dilute C more… well the result seems a bit haphazard, but may depend on film type and circumstances (read at “Important” above).
To alleviate the fogging you need to add “KBr” (Potassium Bromide) or reasonable amounts of Salt (NaCl). With Salt an addition of any form of Iodine (I) appears to be a help in this regard.
T-grain films appears to be the worst in this regard, KBr almost required for best results.
Note: Iodine, Chloride and Bromide are in the same group in the chemical element table – one might ponder on Flouride having an effect too – toothpaste?
