  1. stop bath, short-stop, short-stop bathnoun

    an acid bath used to stop the action of a developer


  1. stop bath

    A stop bath is a photography process solution used in traditional darkroom development. It is designed to immediately halt the action of a developer on a film or photographic paper, preventing further darkening of the image. It usually contains acetic or citric acid. This also helps to neutralize the photographic materials before they are placed in the fixer, hence prolonging the lifespan of the fixing solution.


  1. Stop bath

    Stop bath is a chemical bath usually used in processing traditional black-and-white photographic films, plates, and paper used after the material has finished developing. The purpose of the stop bath is to halt the development of the film, plate, or paper by either washing off the developing chemical or neutralizing it. With the former, a simple water rinse can be used between developer and fixer, but the development process continues for an indefinite and uncontrolled period of time during the rinsing. Where an immediate stop of development is desired, a stop bath will usually consist of some concentration of acetic acid, commonly around 1 to 2%. Since organic developers only work in alkaline solutions, stop bath halts the development process almost instantly and thus provides more precise control of the development time. It also cuts overall processing time, because the required immersion time in the stop bath—typically fifteen to thirty seconds—is much shorter than the time required for an adequate plain-water rinse. As well, by neutralizing the alkalinity of basic developers, it can help to preserve the strength of the fixer, making it last longer.
