I am a little confused about fixers and benefits of different types (ie Acid vs Alkalii) I am currently using TF-4 fix with film partly because of its reputation as helping the pyrocat stain and also because I understand it is easier to wash out therefore assisting in archival matters and conservation of water (an increasingly important matter in the south of England). Am i right so far? I've been out of printing for a while ... I used to use Hypam (which I understand to be an Acid fix ?) after an acid stop bath when printing. Is there any gain to be had by using TF-4 instead? Is the archival matter improved this way? Obviously I would have to not use a stop bath, should I use a waterbath instead? I have also heard that an Alkaline Fix improves the paper emulsion's response to after-treatments like toning - is this correct? thanks in advance for yor help.
