Heico OS Film developer is a highly active solution designed for rapid development of black & white films.
It produces sharp images with moderately fine grain, maximum shadow detail and wide density scale, yet causes no loss in film speed. OS Film Developer excels in development latitude and produces relatively low fog with forced development. The one gallon size makes 10 gallons.
