High Speed Black and White Film
As with all other types of film, these
differences are much less pronounced than they once were. Before, it
was obvious when a print was produced from high-speed film; that is not
necessarily so anymore.
High speed still remains the film of
choice among photojournalists, sports, and black-and-white nature
photographers, where success is dependent on high shutter speeds. Also,
these films can be more readily "push-processed" to higher effective
speeds than other classes of black-and-white films by using high-energy
developers intended for the purpose. Admittedly, pushing does increase
grain, but not enough to make the two to four times speed increase
visually too expensive.
One final thought: Grain is not always
undesirable. Under the right circumstances, it has a role to play,
underlining powerful emotions at the heart of an image. Again, it's
another case of a photographic condition having opposite aspects, on
the surface seeming negative but when turned around in a creative
manner, the result can be positive.
