Platinum Palladium prints
Special editions of handmade, numbered and signed Platinum Pallladium prints at the original tintype 16″ x 20″ size on Arches Platine, 310 gsm, A2
Unlike the silver print process, platinum lies on the paper surface, while silver lies in a gelatin or albumen emulsion that coats the paper. As a result, since no gelatin emulsion is used, the final platinum image is absolutely matte with a deposit of platinum (and/or palladium, its sister element which is also used in most platinum photographs) absorbed slightly into the paper.
Platinum prints are the most durable of all photographic processes. The platinum group metals are very stable against chemical reactions that might degrade the print—even more stable than gold. It is estimated that a platinum image, properly made, can last thousands of years. Some of the desirable characteristics of a platinum print include:
- The reflective quality of the print is much more diffuse in nature compared to glossy prints that typically have specular reflections.
- A very delicate, large tonal range.
- The darkest possible tones in the prints are lighter than silver-based prints. Recent studies have attributed this to an optical illusion produced by the gelatin coating on RC and fiber-based papers.
- A greatly decreased susceptibility to deterioration compared to silver-based prints due to the inherent stability of the process and also because they are commonly printed on 100% rag papers.
