Charles,
I had a moment of time, and a leftover coated piece of paper so I
exposed my Kodak Direct Dupe neg to it and the lower dilution worked great.
It seems, then, that after a certain point the amount of dichromate may
not make that big of difference, except to reduce contrast which is not a
good thing--which is what Sandy said is true of carbon and gelatin anyway.
(In fact, in Sandy's carbon demo to us photo grad students a couple weeks
ago I was shocked to find out the incredibly low strength of am di he used
to sensitize his paper--like, was it, Sandy, 1/2%???) From the way this
negative printed I don't think I need to use a stronger solution. So, in
conclusion, yes, the 6% strength works fine for regular negs.
The even better thing is that with the lower dilution, none of my images are
requiring a clearing bath of pot metabi because there is no gross yellow
left either in the image or the borders.
Happy Thanksgiving to all!
Chris
