Platinum or Palladium printing is the aristocracy of the early photographic processes. Subtle quality, total permanence and ease of working place the platinum-palladium print at the summit of alternative photographic printing. The image is composed of very finely divided platinum and palladium metals that are more stable and longer lasting than silver based prints and are known for their beauty, archival stability and unique, one-of-a-kind print statement. As with the other alternative printing processes, paper is coated with special solutions and, when dry, is exposed under a negative to the sun or sun lamp, the ultra-violet rays are the key here, before being developed in another chemical mix.

Developed first in the 1860s and 1870s, the technique became very popular with fine art printers because of its very delicate highlights and mid-tones and was used extensively until prices rose dramatically during the First World War made the process too expensive. Long thought to be obsolete, platinum printing has in recent years enjoyed a renaissance among photographers who find it meets an aesthetic and expressive need in their personal work. Images can be obtained in colours ranging from blue-black, through neutral greys, to rich sepia browns.

This masterclass offers demonstrations and hands-on opportunity to explore this classic printing technique. No prior experience is necessary.

Over the five days you will:

Expose and process 10x8 film negatives using a large format camera
Prepare platinum/palladium chemistry and coat/sensitise art paper
Expose and process platinum/palladium contact prints using large format film negatives
Explore calibration techniques for production of inkjet negative transparencies
Prepare digital images and print negative transparencies on inkjet printer
Expose and process platinum/palladium contact prints using inkjet negatives

This course covers the following topics

1. Comparison of digital and film negatives
Film grain versus ink-drops, density range requirements

2. Preparation of film negatives for Platinum/Palladium
Achieving necessary density range of 1.7 to 2.0
