Stop bath
Techniques Glossary Stop bath
An acidic bath that is used after the developer to stop development and reduce fixer contamination.
What Stop Bath Does
As mentioned above, stop bath, a weak acid, chemically neutralizes developer, which is alkaline, or a base.
What Stop Bath(s) Is (Are) ...
Stop Bath 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.
Stop Bath
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.
Stopping Down ...
STOP BATH - 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.
STOPPING DOWN - Reducing aperture size - for example, from ƒ/16 to ƒ/22.
Stop bath
An acid solution used between the developer and the fixer. The stop bath halts development and at the same time neutralizes the alkaline developer, thus preventing it from lowering the acidity of the fixer.
3. Stop Bath: In complete darkness, 17- 24oC, agitate for 30 sec. in a 2% acetic acid solution.
4. Bleach- Fix: At 19- 24oC, for 3 min. Room lights can be turned on after the paper has been in the bleach- fix for several seconds.

acid stop bath
a photographic solution, generally acetic acid, used for stopping the action of the developer on a photographic positive, negative, film or paper.
Stop bath. This next step is an acidic neutralizer to slow the effects of the developer. Most procedures call for only thirty seconds in the acidic stop bath.
Stop bath can be reused and will change color when it has been depleted.

the film vigorously in the stop bath and initially in the fixer because gases are released in these solutions and there is danger of air bubbles forming on the film surface. If you allow these air bells, or bubbles, to form, they may cause dark spots.
Another processing point, don't use a strong acid stop bath. Tech Pan emulsion seems to be prone to pin hole spots from a strong acid bath. I use a water stop bath or a weak acid, about 1/3 normal strength.
3 Chemicals: Developer, Stop Bath (You can get by without this) and Fixer. Prepare all of your chemical solutions in advance and according to the instructions supplied with them.
Move the print to the stop bath (diluted per your toner's instructions) when it is as blue as you want it
Wash the print as you would normally do
Dry the print as normal (avoiding heat drying methods) ...
Agitation Keeping the developer, stop bath, or fixer in a gentle, uniform motion while processing film or paper. Agitation helps to speed and achieve even development and prevent spotting or staining.
-Acetic acid - chemical used for stop baths and to acidify acid fixing solution.
-Acetone - solvent chemical used in certain processing solutions that contain materials not normally soluble in water.

Agitation
Keeping a chemical moving: Agitation helps to speed-up and achieve an even development while processing film or paper. It also prevents spotting or staining by keeping the developer, stop bath, or fixer in motion.
Standard lens: Lens with a focal length equal to the diagonal of the film format of the camera.
Stop bath: Solution used in processing to stop development by neutralizing the developer.
