Different types of photographic paper have varying degrees of susceptibility to fading over time. The main cause of this is exposure to UV (ultra violet) light, although humidity, temperature, pollution and acidity are all contributing factors. Exposure to direct sunlight should be avoided, and UV-resistant glass can be used when framing.
Although it may seem too obvious to mention, may people are unaware of what exactly constitutes a print. Put simply, a print is a method of image-making that allows the work of art to be created more than once. The size of the edition (i.e.the number of prints produced of the one work), the significance…
Pigment, unlike dye, is a powder made up of tiny granules that will not dissolve completely in solution. This means that pigment-based inks leave particles of pure colour bonded to the surface of the paper that they are printed on. The resulting images can thus appear very rich and physical, densely saturated in colour –…
Silver salts Silver salts are light sensitive chemical compounds. When exposed to light – either in a camera (in the case of film and negatives) or in the dark room (photographic papers) – the silver salts react by darkening in proportion to the amount of light reflected from the subject. Silver bromide Print Silver bromides…
P.F.T.s, or Print Film Transparencies, are positive colour reproductions from original negatives, produced as transparencies.
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 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…
