Hi Marc, it's beatiful. From your explanation, I understand this is P.O.P. Palladium / Ziatype "sans Palladium" right? Have you tried to add Sodium Tungstate (NaOW) to the coating solution? NaOW is used to lower the emulsion contrast in P.O.P. Palladium / Ziatype. Certainly that will have an effect over the image color (it warms the color w/ Palladium) but I think it's worth to try - to see what happens. BTW, what was the strenght of the gold solution? (5%?)
Regards,
Loris.

Subject: gold print
on this list, we like show what one knows make.
I have realized a gold print on Richard de Bas 300 gr.paper for an American photographer +David Seidner in 1994.
To realize this print, I print as for the platinum with the method ammonium ferric oxalat and humidification before lighting UVA with the same formulate that the platinum, substitute simply the platinum by the gold.
Only, as the contrast with gold in these conditions is very strong, I have realized a film with very weak contrasts.
You can see it on this announcement, before I do separate.
This easy printing system and cheaper becomes interesting with inkjet films.
And then that can be a good introduction before pass to the chrysotype of Mike Ware...
