Stop bath

dictionary
Written by Martin Kaninsky

A chemical bath used after the developer in film and print processing. It stops development quickly, usually with a weak acid such as acetic acid.

The stop bath also protects the fixer from contamination. Some photographers use plain water instead. See also darkroom.
