P.F.T.s, or Print Film Transparencies

A C-type colour resin-based paper made by Fuji. It offers excellent colour reproductions and has superior archival properties (over 70 years if kept in controlled conditions).

A sheet of transparent film coated with silver salts which react when exposed to light (usually in a camera). In black and white negatives, one layer of salts reacts to white light (the full spectrum of light). The result is a reversal of normal vision: the shadows are light, the highlights dark. In colour negatives…

A stencil is made up for each colour of the image and put over a fine fabric mesh that is stretched over a metal frame. The coloured ink is spread over the mesh and stencil and the ink falls through the stencil to the underlying material (usually an art paper) to produce the image. The…

Also known as heliogravure, photogravure is arguably the finest photomechanical means of reproducing a photograph in large editions. Copper plates are acid-etched directly from an original silver print; the etched areas then hold differing amounts of ink in order to correspond to the tones of the original print. If prints remain untrimmed, the impression of…

Chloro-bromides share the features of all silver gelatin prints, giving deep rich blacks and crisp whites on a high gloss paper, as well as having good archival properties. Compared with silver bromides or silver chlorides, they have a warmer brownish-black tone.

A particular type of reversal (R-type) colour paper and printing process which gives strong colours (often with striking reds) and creates a long-lasting print. Printing in this way from a positive image results in exactly the same colour saturation as the original, and greater contrast.
