RE: Mike Ware's POP Pt./Pd. Pt

Hi Loris,

Will get the lithium chloride. Your advice has been outstanding so far, and I am very pleased with the results.

Just wondering, have you done any work with AFO and kallitype? The clearing of prints in Disodium EDTA made with FAO and Ammonium Tetrachloropalladate (II) is so quick and easy I am wondering if the procedure can be adapted to silver nitrate.

Good news Sandy. I'm glad that you like the alternative sensitizer. Do
yourself a favor and also purchase some (cheap, B&S has it) Lithium
Chloride - to make some Li2PdCl4. (Don't skip this - it's quite a good
hint IMO.)

My pleasure. Best regards,

Subject: 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.
