may require an active developer to bring out as much of
the image as possible, while a film exposed under
normal conditions requires a normal working developer.
There are many different developers, each provides
different activity and quality of development. The actual
choice of the developer to use depends on the type of
film, conditions under which it was exposed, type of
negative required, and the developing time that is best
for your development method.

magnifications are used to make prints. The tendency to
use small-format film and make large enlargements has
resulted in the need for fine-grain developers.

negative tends to reduce the graininess of the negative.
However, this may not contribute significantly to a
reduction in the graininess of the final print. Any
advantage achieved by lowering negative contrast may
be offset by the need to use a higher contrast printing
filter to print the negative.

High-definition developers may increase film speed by
one or two f/stops, but they also increase graininess.
High-definition developers are recommended for use
only with fine-grain (slow or medium speed) films.
