[alt-photo] Re: BLEEDIN' PT/PD PRINTS

BOB,
Mine, too, occurred during the early part of development.  The solution would stream out of the dark areas of the print.

Eric, you say check balance of pt/pd mix.  I am assuming you mean make sure enough ferric, correct?  What I found is my eyedropper for pt/pd solution was bigger than my one for ferric, hence I was getting more pt/pd salts than ferric.  I corrected that as one of the measures. Is this what you are saying?
