Negative reducers print reduction

This dilution is for correcting slight overexposure or overdevelopment of fine-grain negatives and overall print reduction (bleaching). For print reduction follow the instructions given under Print Reducers, Farmer s Reducer. 

NOTE 1 Before reducing a negative or print clean thoroughly with film cleaner to remove any surface grease left from handling. To promote uniform reduction pre-wet the emulsion in a wetting agent such as Edwal s LFN. 

Ammonium Thiosulfate Reducer is prepared by adding citric acid to an ammonium thiosulfate rapid fixing bath, such as ATF-5. This reducer can be used to remove silver stains and dichroic fog from negatives, and for the reduction of both prints and fine-grain negative materials.
