Hypo Clearing Agent (Kodak’s name for their washing aid designed to more efficiently remove fixer from films and papers) is not really necessary for film or resin coated papers. Wash times for these products are short; and while there’s no harm in using a wash aid, there is no real advantage either.
Kodak Hypo Clearing promotes removal of fixer from films and fiber-base papers to shorten wash times and make washing at lower wash-water temperatures practical.
Moreover, Why do we wash prints?
In photography, washing is an important part of all film processing and printmaking processes. After materials have been fixed, washing removes unwanted and exhausted processing chemicals which, if left in situ, may cause deterioration and destruction of the image.
Secondly, What is the purpose of stop bath?
Stop bath is a chemical used for processing black-and-white photographic films, plates, and paper. It is used to neutralize the alkaline developer, thus halting development. Stop bath is commonly a 2% dilution of acetic acid in water, though a 2.5% solution of potassium or sodium metabisulfite works just as well.
Simply so, What liquid is used to develop photos?
Common chemicals used as developing agents are hydroquinone, phenidone, and dimezone. The developing mix must have high acidity, so chemicals such as sodium carbonate or sodium hydroxide are often added to the mix.
Is a stop bath necessary?
No, you don’t have to use stop bath. The acid of stop bath immediately halts development and prevents the alkaline developer from exhausting your fixer. So if you need absolute precision in developing time or want to absolutely maximize the life of your fixer you can use stop.
