What is the primary purpose of the
base portion of photographic film
and paper?
1.
It prevents the emulsion
from being damaged
2.
It suspends the silver halides
3.
It supports the emulsion
4.

2.
Morgan and Morgan Corporation
3.
International Standards
Organization
4.
Film Speed Organization of

A film may be assigned more than
one film speed for which of the
following reasons?
1.
Because the film may be
used in hot or cold weather
2.
For use with fast or slow
shutter speeds
3.
Because the emulsion may
respond differently to
different qualities of light
