The
production of fine grain
in a negative is dependent on, in the first place, speed of the film
and the choice of developer. The object is to keep the structure of
the grain in the emulsion as small as possible so that it does not
show up in the enlargments. Fine grain developers are best suited to
films of medium speed about 125 ISO and above.
Some of
the best known fine grain developers:
Ilfords Microphen and ID11, Tetenal Ultrafin, Kodak D76, PMK Pyro is
a staining developer that produces a fine grain and for the new grain
techologies: Kodak HC110 and T max, Ilford LC29 and Tetenal Ultrafin
plus, just to name a few.
