I seem to be experiencing a problem with selenium toning My Adox Vario G paper. I've tried 9:1, 3:1, and 20:1. and although I can dectect some deepening of D-MAx at the lower dilutions image color is totally unaffected unlike forte which for me even at 20:1 I get a very deep brown with a hint of red. Anybody out there had any experience with this paper and selenium? Could my toner just be used up? It still tones forte ok.
