CORRECTION: Re: my pigment dilutions
I went back and redid my math and I was a tad off, and then decided to make
the math easier to understand, plus uploaded another 3 colors. So now it
says the amount of TOTAL volume that the tube of 15ml pigment is in.
To put my money where my mouth is, I then went ahead and mixed up those
stock mixes (the stronger one--the weaker ones on the left are essentially
cut in half) to make sure I was accurate and I am. So there you have it.
But of course, NOTHING is simple in my household--I ran out of gum so had to
mix up another batch, ran out of pigment and had to get some more, blah blah
blah so it was a sacrificial day to the gum universe. Just to do these two
David, the swatches further down the page are just comparing stock solutions
of one 15ml tube in a total volume of 60ml gum--very strong and that
strength only used with an occasional yellow and raw sienna. I make a gum
curve for the three colors, but when I make a softer colored print I just
use the same negs, so I am not too perfect about it.

Subject: my pigment dilutions
At this URL I posted a visual of my pigment dilutions:
CAVEAT: I am NOT telling anyone how to do their coatings, and the image
may be totally meaningless to you, but it is what I do. Private practice
one might say!
The amounts look really odd, but to explain them, I have all my stock
pigments mixed in 60ml nalgene bottles, one 15ml tube to a TOTAL volume of
60 ml. At time of use I dilute that stock different amounts depending on
the effect I want. Loris prompted me to be more exact at what I actually
do, so I went in the dimroom and did all my measuring and calculating and
found that I usually mix my stock mix of yellow 1+1 gum at time of use, my
stock mix of magenta and thalo pretty equal at 1+5 at time of use, or else
a straight yellow stock solution, combined with magenta stock + plain gum
at 1+2 and thalo stock + plain gum at 1+2. But at the bottom of the
picture of my test strips I figured out the actual amount of tube pigment
in the final amount of gum so it looks more understandable. At the top I
have a mixture of drops of my stock mixes showing a neutral grey that they
So thanks, Loris, for keeping on asking these questions so I could finally
be less "kitchen cooking" and more exacting about it. See, a lot of times
I use a scant tsp of this and an overflowing tsp of that when I am making
my coating solutions.
Speaking of Visual Server, this is why I love the site, too, because I can
easily plop these images in whenever I get the urge.
