ISO Sensitivity
“ISO sensitivity” is the digital equivalent of film speed.
The higher the ISO sensitivity,
the less light needed to make an exposure, allowing higher shutter speeds or smaller
apertures, but the more likely the image is to be affected by noise (randomly-spaced
bright pixels, fog, or lines; noise is particularly likely at settings of Hi 0.3–Hi 2).
Choosing Auto allows the camera to set ISO sensitivity automatically in response to
lighting conditions.
