ILFORD MICROPHEN is a fine grain film developer based on the Metol substitute Phenidone which gives an effective increase in film speed. A speed increase of up to half a stop is usual with most films, producing enhanced shadow detail. However faster films such as HP5 Plus, DELTA 400 and DELTA 3200 can be used with extended development times in Microphen to give a greater 'push' in speed.
Many developers that give an increase in film speed usually produce a corresponding increase in grain size; MICROPHEN is formulated to overcome this disadvantage.
