Just two drops of low-foaming, non-ionic LFN makes a pint of developer and will prevent air bubbles and floating dust particles from causing pinholes. Two drops per pint of water for use as a film rinse will drain evenly and completely. An LFN final rinse solution for RC prints, which are to be air-dried by hanging, will promote even drying and cut drying time by about half.
LFN foams much less than other wetting agents and bubbles disappear in seconds. LFN is non-flammable, non-corrosive and harmless to photographic materials and equipment.
