Other Chemistry

Other chemistry covers auxiliary products that complement developers and fixers in analog processing. The category includes stop baths, wetting agents, stabilisers, washing aids, emulsion hardener, anti-fog agents and sepia toners from Tetenal, Bellini, Foma, Ilford and Ars-Imago.

A stop bath halts development and extends fixer life, a wetting agent helps film dry without marks, and a washing aid shortens washing time. Toners such as the Foma and Bellini sepia sets give black-and-white prints a warm brownish tone. Check whether a product is intended for film, paper or both.
