Basic Terminology 1
• ISO film speed
The ISO film speed indicates the
film’s sensitivity to light. The higher
the film speed, the more sensitive
the film is. The more sensitive the
film is, the less light is required to
obtain
a
standard
exposure.
Therefore,
a
high-speed
film
is
suited for low-light situations. The
ISO film speed is standardized by
the
International
Standards
Organization (ISO). The EOS-3 can
display a film speed from 6 to 6400.
