Mike Ware's POP Pt./Pd. Pt
Title: Mike Ware's POP Pt./Pd. Pt I finally received
some ferric ammonium oxalate today and was able to do a few tests with
Mike Ware's POP Pt./Pd. process. The results were very encouraging.
The Dmax I was able to get with the sensitizer of FAO + Ammonium
Tetrachloropalladate (II), on the first try, was definitely
better than I have been able to get with palladium printing using FO
in my working conditions. I am working in a room with about 60%
RH, which gives a sepia color print with straight palladium. I am also
exposing by time, not visual inspection.
I would also add that working with the FAO is a real delight compared to FO. It mixes up quickly and completely in about 5-10 minutes, and results are very low fog. I am using Mike Ware's recommended post-exposure processing, which you can find oin his web site (http://www.mikeware.co.uk/mikeware/Platino-Palladiotype.html), but I have also found that I can get contrast control with the Disodium EDTA with dichroamte. Mike does not specifically recommend this approach, as I recall, but I find that it gives a lot of flexibility to the process.. In any event, I thank Loris Medici for putting me on the potential advantages of FAO. Lots of potential here I believe. Sandy King
