Fine grain film developer which gives an effective increase in film speed. A speed increase of up to half a stop can be achieved with most films but faster films such as HP5 Plus, DELTA 400 and DELTA 3200 it is more. Many developers that give an increase in film speed usually produce a corresponding increase in grain size; MICROPHEN is formulated to overcome this disadvantage.
