Originally taken back in 1978 with my old Leica IIIf, on Tri-X @ 200 ISO, developed in Rodinol. Recently I made an enlarged diapositive on Plus X and and contacted it onto another sheet of Plus X. Both processed in straight Dektol. The final print is a Ziatype using lithium ferric oxalate, lithium palladium. platinum, and NA-2 for contrast. Yes, if you use lithium ferric oxalate, or sodium ferric oxalate you can use NA-2 with potassium chloroplatinite.
