Factors affecting degree of development:
The density obtained in a developed image depends on the nature of the
emulsion, the exposure it has received, the degree of development,
temperature and compatibility of the film and developer. With any emulsion,
the degree of development depends upon the time of development, temperature
of the developer, strength of, and freshness, exhaustion, the degree of
agitation of either the material or solution, how active the developer is,
etc.
If film does not receive any agitation, developer action slows. This
happens because the developer in contact with the emulsion, becomes
exhausted. This does not happen when agitation is done. It is important to
do this properly because of the likelihood of streaks and mottle.. If there
is no agitation, exhausted developer loaded with bromide can flow across
the emulsion from dense highlight areas and produce uneven streaks.
My 2 cents worth,
