speed controls the
sensitivity of the film or
the sensor that absorbs
the light. The higher
the ISO speed, the
more sensitive the film
or sensor is to light. The
word ISO isn't

inside the camera is

sensor is proportional
to the exposure
time. 1⁄500 of a second
will let half as much
light in as 1⁄250.
