Can someone recommend ... or other method ...
You've a really pour way of processing large prints.
Give yourself a break.
Add 24 ml of A. Thio. concentrate to 1 lt. of water. Give it
a stir then into the fix tray. Fix for three minutes constant
agitation. Good for 1, 16 x 20.
After you've dumped the fix rinse with 1 lt of water, hypo
clear with 1 lt. of 1% S. Sulfite, rinse again then hold or
wash.
Although I'm not yet doing anything close to 16 x 20s, I
do use all chemistry one-shot. BIG PLUS with that very dilute
one-shot fix; single bath Archival results.
Quarter the amounts and see how it goes with your
materials and methods. Dan
