Very Rare Paget Plates Discovered

Conservators Darren Weinert and Brooke Shannon, of the NFSA’s Still Image Services team, were surprised and delighted recently to discover a number of Paget plates in the Collection.

The Paget process was a very early colour photography process patented in Britain in 1912 and marketed by the Page Prize Plate Company in 1913. The process saw moderate success and was discontinued in the early 1920s, which makes the plates very rare.

The system used a glass plate, which was a standard black-and-white photographic plate and a coloured screen, comprised of a series of red, green and blue filters laid down in a regular pattern of diamond shapes, called a reseau. The screen was placed inside the camera in front of, and in contact with, the emulsion. The exposure was then made through the coloured screen and the negative was then processed.

The resultant negative looked like a standard black-and-white negative, although with a noticeable crosshatch patterning. The negative was contact printed to produce a black-and-white positive image and a viewing screen with more intense colour filters was used in exact register with the developed positive plate to produce a composite colour image, the final Paget Plate.

Still Image Services Officer Brooke Shannon says that the plates were discovered in a collection of family images by Franklyn Barrett. Barrett was a film cameraman and director, most famously known for directing the Australian films, The Breaking of the Drought (1920) and A Girl of the Bush (1921).

The collection contained only seven of the plates and these are the only known Paget Plates in the NFSA collection, although there may be others previously presumed to be ordinary black-and-white slides.

Brooke says that the Paget plates, which are beautiful to look at, are a very important discovery.
