Re: another 3 layer gum attempt
Paul.
It looks to me as though you havent developed the yellow print for nearly as long as you should. Try leaving it longer or spray it with the shower head.

Hmmm...ok, I see that. I just brushed some out of my pigment/gum mix and can
see that it should be a bright sunny yellow, of course.
For my testing I was using info on your site, re exposure, but I think I'm
not understanding it correctly. You say that you should expose the test
strip for the max amount of steps remaining after development, and I keep
pushing exposure to move tone up the wedge, which I can see is wrong.
But...hmm. In your reply, you mention using a fairly contrasty neg at under
a minute in the sun...dang! I was originally using my digi-palladium negs
which are approx DR 2.0 or slightly higher at 2 1/2 minutes, but the results
were light, light, light (

this is the stuff that stumps me.

Wow, if that's cadmium yellow light, then it's way overexposed; I've
never seen a pale yellow do that before. Caveat: I haven't worked
with cadmiums much except for test prints, as I find them too opaque
for my taste, but it didn't do that on the test prints I made with
it. I'd say try cutting the exposure in half. My sun exposures with
a black (fairly contrasty) negative tend to be under a minute.
I agree that it's more likely overexposure than staining; that
doesn't look like stain to me.
