Some Platinum work to get ready for the next show.

[Barry Kirsten]

Beautiful, Tri. Straight Pt or Pt/Pd? - I'm keen to try Pt myself.

Barry.

[Tri Tran]

Thanks Barry. Straight Pt won't give you the warm tone, my ratio Pd/Pt is usually between 70/30 or 80/20 depending the density of the neg. I'm ratio method guy and develop with Potassium Oxalate.

Beautiful work, Tri! But I always wonder why it's called "platinum print" when platinum itself is just a small percentage… Wouldn't it rather be "palladium print"?

[Barry Kirsten]

Tri, I have seen pure Pd prints and they are usually too warm for my taste. These are beautiful in every respect, including color. I keep coming back to both of these, particularly the second one. May I ask, what paper do you use, and why pot. oxalate rather than ferric oxalate?

Many thanks, Barry.

Everyone knows what platinum is -- few know about the metal palladium...platinum is much more expensive sounding too!

I use about the same mix as Tri, and the same developer. I use mine warm -- somewhere around 100F.

I will not swear that the print is very close to this color

Wawona Tunnel
Yosemite National Park
8x10 Pt/pd print

Taken between mid-night and 2pm to avoid traffic -- I had to move the camera a few times when a car would show up. One could hear them coming from quite a ways, so I did not worry too much about getting hit from behind while under the darkcloth.

Potassium Oxalate is the developer that Tri is using, he is still using ferric oxalate in his sensitizer ratios. Photographers have several options when it comes to developers for their platinum and palladium prints, the most common of which are ammonium citrate and potassium oxalate, and each developer yields a tonal range with different characteristics. These prints sing, nice work.

Ahh... thanks, Dave. I need to do more reading before I get into this. Yes, these prints really do sing.

Looks more like silver prints to me on...Ilford?

Platinum is considered is the precious metal as known by the trade so I guess people call it platinum print even though there is only a small percentage used.

I mostly use Weston Paper . It has the warm tone, naturally and it absorbs the chemical well. Great Dmax though. My favorite papers are Weston and Crane Natural.

Don't be surprise if your print and mine are not the same tone. I did the same thing with Patrick Alt years ago as we compared prints. They never look the same although we all use the same chemical distributor, same method and same mix . It's another virgin territory

Thanks Dave for the clarification. Glad to see you here on the forum. For those of you who don't know, Dave Hyams is former employee for Bostick and Sullivan . I have known and been working with Dave for many years . Very knowledgeable about the alternative process , the chemical and formula . Another great platinum specialist.
