Once hugely popular, today one of the rarest and yet most permanent photographic techniques. Coming from the 19th century, the platinum/palladium print produces images formed by the most precious metals: platinum and/or palladium.
Prints produced with use of these techniques are characterized by unrivalled tonality and permanence. The rarity of the technique is caused not only by the cost of chemicals used in the process but also by the difficulties involved in getting the print right.
The technique was used by many of the greatest photographers of the past such as Irving Penn or Edward Steichen to name just two. The latter often combined it with gum bichromate, which is also my favourite combination.
