Platinum-Palladium print. The platinum-palladium printing process is a photographic technique renowned for its exceptional aesthetic and archival properties. Compared to conventional black and white silver prints, platinum-palladium prints exhibit an expanded tonal range, three-dimensionality, and a uniquely luminous quality. Salto Ulbeek platinum-palladium prints are all produced on 100% cotton paper, combining historic and contemporary techniques developed in-house for the company's exclusive use. Because platinum and palladium are among the most stable elements in the universe - more stable than gold - these prints can last thousands of years., 95 × 75 cm
