Platinum prints, also called platinotypes, are photographic prints made by a monochrome printing process involving platinum. Platinum tones range from warm black, to reddish brown, to expanded mid-tone grays [ clarification needed ] that are unobtainable in silver prints.

The platinum print process is based on the characteristics of light-sensitive iron salts, which react with platinum salts to form platinum metal. A sheet of paper is coated with a solution of these salts to make it sensitive to light.

For people who collect photographs, platinum/palladium prints are renowned for their beauty, archival stability, and unique, one-of-a-kind print statement. Made from the salts of platinum and palladium, these prints are also called “platinotypes” or “platinum” prints.

The following step-by-step guide illustrates the basic ma-terials and methods used to make a print in platinum or palladium (platinum/palladium), or a combination of both (platinum-palladium), by the traditional developed-out and alternative printed-out processes.6. 1. Sensitization.

Platinum printing is the ultimate in printing flexibility. This flexibility is achieved through the photographer’s selection of paper (with many choices for weight, surface and color), contrast level and print tone.

2010年3月2日 · Yet I have found that by adhering to several steps, platinum printmaking can be relatively simple and very rewarding. The three basic components of platinum printmaking are a shot glass, a platinum cocktail mixture, and “a little help from heaven” – the sun. Getting started with platinum printing

2020年1月24日 · To create a platinum print, a negative is placed in direct contact with photographic paper that has been sensitized with a solution of iron and platinum salts, often applied by hand. After exposure, while the paper is submerged in the developer, the salts react to produce platinum metal in the exposed areas.

Patented in 1873 in England, the platinum printing process (sometimes known as platinotypes) enjoyed widespread use between 1880 and 1916. For these prints, a light-sensitive solution of platinum and iron was coated directly onto paper and exposed under a negative.

experimented with platinum printing during two distinct periods: 1890–96 and 1904–13. Kühn’s Platinum Prints, 1890–1896 In the early 1890s Kühn undertook a two-month pho-tography expedition through Dalmatia and Herzegovina, then part of the Austrian monarchy. In Ragusa (now Du-brovnik) he met with the inventor of the platinum print-

Platinum prints are not only exceptionally beautiful, they are among the most permanent objects invented by human beings! The platinum metals (platinum and palladium) are more stable than gold. Incredibly, a platinum image, properly made, can last thousands of years.
