Definitions for "Stop Bath"
Keywords:  bath, fixer, halt, rinse, acetic
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.
