I've had good success developing expired films at reasonably standard temperatures but would now like to try lowering the temperature to see if fog can be reduced or eliminated.
From Googling, HC110 is the developer that's recommended for old or expired films, but while there are plenty of references to reducing temperature in order to minimise fog, I haven't managed to find anything which states the lowest temperature at which the HC110 will work properly (without its hydroquinone losing activity).
There are a number of posts where development has been carried out using very concentrated HC110 at almost 0*C, but I don't believe this necessarily means that the HC110 is working as intended. Kodak themselves quote temperatures from 18*C.
Does anyone know the lowest temperature that HC110 can be used at while retaining the activity of both its developers? 16-17*C? Or lower?
Thanks for any help!
