My question would be why bother?? In general, it is much more difficult to
get a smooth, rich print from straight Pt than from sraight Pd or a Pt/Pd
mix. Plus, the Pt solution costs roughly 4x as much as the Pd solution. If
you're looking for more neutral tones, use ammonium citrate developer or
use the Ziatype process.
