Silver
Undyed silver halides are sensitive
to what color of light?

Blue
2.
Green
3.
Yellow

What portion of photographic film
or paper is light sensitive?
1.
Base
2.
Emulsion
3. Antihalation backing
4. Overcoating
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. It contains sensitizing dyes
Because of the nature of the
recording medium used in still
video and digital cameras, they
must be loaded in complete
darkness.

Exposure to light causes what
invisible change to a photo-
graphic emulsion?
1. Film speed
2. Development
3. Black-metallic silver
4. Latent image
Learning Objective:
Identify
film characteristics that you
must take into consideration
when selecting a type of film
for a photographic assignment.
The inherent property of a film
emulsion to respond to light is
known by what term?
1.
Film speed
2. Spectral sensitivity
3. Exposure latitude
4. Emulsion definition
What organization is responsible
for the approval of a uniform set
of film-speed standards?
1. Eastman Kodak Company
2. Morgan and Morgan Corporation
3.
International Standards
Organization
4.
Film Speed Organization of
America
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
4. To provide the photographer
with an option of shooting fast
or slow subject motion
