[alt-photo] Re: to shrink or not to shrink (registration)

[Katharine Thayer]

Hey, looks great, and beautifully registered.   A couple of   
questions/comments:

(1) I assume your indigo isn't really indigo (PB 66, a fugitive  
pigment no longer used in any watercolor paints) but one of the  
mixtures of blue (a different blue in each case) with lamp black that  
are currently marketed under the name "indigo" by several paint  
manufacturers.  Or are you using powdered PB66?

(2) It will be interesting to see what your final print looks like  
and whether you're happy with it.   I was looking at this as a  
finished duotone, and found the ochre-brown cast very appealing, but  
now that I realize (from another post that came in while I was  
writing this) that you mean this to be the first two layers of an  
(unsaturated) tricolor gum, I have different thoughts.  It  depends  
entirely on what effect you're hoping to achieve, so this might work  
perfectly for what you want to do, but in general if you're hoping to  
finish with a somewhat neutral and somewhat realistic-ish color  
balance, then you'd want the overall color cast of the print after  
the second layer to be roughly the color complement of the third  
layer.  But if that's not important to you, or if you're intending an  
orangeish-brown final print (actually that might be cool, depending)  
then it doesn't matter.
