Term used in multiples publishing when only a limited number of any print, book, sculpture or other artwork is produced. Editions can be limited to almost any number depending on the nature of the work.
A positive is, obviously, the opposite of a negative – that is, it is an image which is not reversed. Positive images are made through a double negative: silver salts react to light producing a negative which, when projected onto photographic paper (more silver salts), produces a positive.
P.F.T.s, or Print Film Transparencies, are positive colour reproductions from original negatives, produced as transparencies.
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.
A photogram is a photograph made without a lens or camera: objects are placed directly on top of a sheet of photographic paper which is then exposed to light. Where the objects obstruct the light, the paper remains unexposed (light in tone), while the rest darkens through exposure.
