Setting the ISO Speed
*
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.
The camera can be set between ISO 100 and 1600 in 1/3-stop
increments.
In the <

within ISO 100-400.
