[alt-photo] Re: 3 color gum and PDN calibration?

[Mary]

That's gum printing for 'ya.

I use M Graham Ni Azo Yellow, and as I said, my exposure times are 
shorter, not longer. Otherwise yellow is overwhelming.
I print in the order blue (cyanotype), yellow, magenta (Mgraham quin rose).

So many variables, so little time...

  I agree with Henry that yellow is longer than the other two exactly as 
he says. In practice, how this translates (loose, like everyone else 
recommends) is my timer is usually at 6 minutes and then pull the cyan 
and magenta at about 5 and the yellow if I forget to walk in there for 
several minutes I don't care. If I forget on blue that is a different 
story. Busted.
