I know that Karl Koenig uses a 3:1 gum/pot
dichromate ratio for printing the positive, but I was wondering if anything
would be amiss should I use my usual 1:1 (sans pigment, of course) since my gum
negs are tuned to that already and I have a known exposure
factor...
3:1 would make for a more contrasty gum deposit, I
would guess but I'd have to expose longer than my 1:1 mix, right?
Someone, maybe Katherine (?) had a rule of thumb
for exposure times with differing ratios/amounts of dichromate...?
Thanks...Paul
