Photographic Papers have been used since the beginning of all negative-positive photographic processes as invented by Nicéphore Niépce (France/1824-Heliography) and popularised by William Fox Talbot (Great Britain/1841-Calotype).
Traditional Photographic Papers are still sold commercially today (2005).

I. Papers used for negative-positive photographic processes. (e.g. the Gelatin-silver process). This is the most common form of analogue photography. Even though slide film produces a positive image of a positive scene, the common process for the development of photographic transparencies (E-6) is actually a positive-negative process applied twice.

Photographic Papers are further distinguished by the characteristics inherent in their different Photographic Emulsions. Black-and-white Photographic Paper is available in different grades which are numbered 0 to 5, with 0 being the softest, or least contrastful paper grade and 5 being the hardest, or most contrastful paper grade.
Photographic Emulsions are also produced in a variable contrast type which permits the selection of any grade between 00 and 5. Variable contrast Photographic Paper is actually co ...
