Canon 0296B002 Digital Camera User Manual

The ISO speed is a numeric indication of the sensitivity to light. A higher
ISO speed number indicates a higher sensitivity to light. Therefore, a
high ISO speed is suited for low light and moving subjects. However,
the image may look more coarse with noise, etc. On the other hand, a
low ISO speed is not suited for low light or action shots, but the image
will look cleaner.
