The camera’s sensitivity to light can be adjusted according to the
amount of light available. The higher the ISO sensitivity, the less
light needed to make an exposure, allowing higher shutter
speeds or smaller apertures. Noise (randomly-spaced bright
pixels, fog, or lines) is however more likely at a setting of Hi 1,
which is equivalent to ISO 25600). Choosing Auto allows the
camera to set ISO sensitivity automatically in response to
lighting conditions; to use auto in P, S, A, and M modes, select
Auto ISO sensitivity control for the ISO sensitivity settings
item in the shooting menu (
0 227).
