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.
