Temperature of D eve loper must not e xcee d 70 degre es
Fahr ., as above that point there 'is danger of th e film -frill-
ing. 45 degrees Fahr. is the lowest temperature at which
the developing powders can be dissolved and eve n at this
te mper ature the powder mnst be finely crushed and added
slowly to the water.
It is best to use the normal temperature (65°) when pos-
sible as the use of a developer that is colder than normal
has a slight tendency to increase the contrast in a nega-
tive while the use of a developer warmer than normal
slightly flattens the resulting negatives.
