In response to my request for suggested film/developer combos (thanks!) to make
in-camera negatives for platinum prints, a few folks suggested overexposing and
overdeveloping the negative. Dick Arentz however recommends (in his booklet)
underexposing one stop and developing 1 1/2 to 2 times normal (he uses Tri-x Pro
and D-76). He has also stated (in an interview) that he gives negs destined for
straight palladium more development than those for platinum/palladium.
I know what a good silver neg should be but I have never seen a good neg for
platinum -- looking at a final print doesn't help much. I don't have a
sensitometer so I'll just have to eyeball it. Though I've already bought
supplies, I'm reluctant to even start in with printing til I've got something
decent to work with. Hope my newbie questions aren't boring you to tears.
