Darkroom material. An acid rinse, usually a weak solution of acetic acid, used as a second step when developing black-and-white film or paper. It stops development and makes the hypo (fixing bath) last longer.
A chemical solution used to halt the development process in film and paper prints when a sufficient degree of color saturation has been reached. Experienced photographers often substitute a solution of white vinegar for commercial stop baths since it evaporates leaving no residue and this simplifies the washing process.
Stage in processing which arrests the previous solution.
an acid bath used to stop the action of a developer
an acid solution used to arrest development by neutralizing the alkaline developer with which the photographic material is saturated as it leaves the developing bath
Stop bath is a chemical used to prevent development by neutralizing unwanted developer.
An acid bath or rinse (usually a weak solution of acetic acid) for stopping the action of a developer before fixing a negative or print.
Acidic bath used between developer and fixer. Halts the development process as developer requires an alkaline environment to function. test strip Print with a series of consecutive exposed strips ranging from too dark, to, too light. Used to gauge required exposure for a print
Stop bath is the second of three chemical baths usually used in processing traditional black-and-white photographic films, plates, and paper. The sequence is: developer, stop bath, fixer. 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.
