Digital colour coupler Colour coupler prints, or chromogene prints, are very similar to standard C-type prints, but the silver salts ‘couple’ with coloured dyes, rather than being replaced by them. The end result is very similar to standard C-type prints. Colour coupler prints have the benefit of using the same extremely light-sensitive silver salts as found in silver gelatin prints, but they form high-resolution colour images rather than black and white ones.
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.
NTSC VHS video format used in North America and Japan. PAL VHS video format used in Australia and Europe (excluding France).
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.
Dye, unlike pigment, dissolves completely in solution (pigment-based inks leave tiny particles floating in the solution). This means that dye-based inks are entirely absorbed into the paper that they are printed on – the image is in fact a highly controlled stain. The resulting images can thus appear very slick and even, with a vast…
An Interneg produced by digital means, rather than traditional photographic methods. Digital internegs are made by scanning an original negative or its positive image, before laser-writing the digital negative.
Matt, gloss, supergloss, satin and pearl are all finishes available on different paper types. Satin and pearl are different names for the same finish (somewhere between gloss and matt).
