Re: CORRECTION: Re: my pigment dilutions
Thanks Christina, for that.
By the way, my bathroom is very similar to yours most of the time. I get lots of flak for it too! Are you at all concerned about chrome contamination? My wife is. She seems to think that we'll all die horribly if I persist.

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.
