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?



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