You should maintain a log of the different types of
copy jobs completed in your area of responsibility. With
the continual changes in photographic film, processes,
and equipment, you must always perform tests (whether
it be standard copy or slide duplication) to achieve the
highest quality product possible. Camera distance, light
source (K), light distances, film type, filters, camera
settings, and processes should all be included in the log.
By maintaining a log, you eliminate the necessity for
photographic testing every time a routine copy job
comes into your work center.
