Hi,

I am in the middle of printing Pt/Pd, and I am a little confused about the dichromate method and the change of the density.

It seems that as I change to a higher contrast developer, the density goes lower. So, I need to change the time every time I change the contrast. I was under an impression that I adjust the highlight by time and shadow is go deeper as I change the contrast. Was I totally mistaken to think this way?

How do people usually figure out the time and contrast with this method? Any good idea for the work flow?

Thanks.

Warmly,

p.s. by the way, I am using potassium dichromate like Sandy suggested...
