[LargeFormat] Making Water in the Dark

[Frank Filippone]

I think for B+W you need to read the latest in Ilford's literature on
archival printing.   They propose that we fix too long, getting the fixer
deep into the paper, causing long wash times to remove that fixer.  Their
proposal is to.use a strong quick ix, folloed by a 2 stage quick wash....
and they claim this is archival in process.....

For film, JOBO has published that it is the NUMBER of changes of wash that
get rid of the fixer.... they state 20 changes of water is sufficient to
archivally process B+W films.....  At 170mL per wash, that is still about a
gallon......

I think some reading in this area will prove to somewhat alleviate the
problem, but whatever you do, don;t recycle the water into yor examining
room... the patients would prefer not to have this kind of "fixed" teeth.
