It s a really "rapid" fixer?? ( a normal fresh fixer as hypam with
tmax employ about 8 minutes to eliminate the magenta cast) ...
I don't use T-max film but by all accounts it is slow to fix.
That is due to it's having some silver iodide as part of the
emulsion's silver halides. The iodide is extremely insoluble
so takes more time and more fixer.
Give or take some little you can fix twice as much film and
in half the time using other than iodized films.
BTW, is Acros an iodized film? Anybody? Dan
