Setting The Iso Speed; Iso Speed Extension - Canon EOS 1D MkII Instruction Manual

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 finer.
The camera can be set between ISO 100 and 1600 in 1/3-stop
increments.
¡
At higher ISO speeds and higher ambient temperatures, the image will
have more noise.
¡
High temperatures, high ISO speeds, or long exposures may cause
irregular colors in the image.
