ISO
The ISO function allows you to set the sensitivity of the camera's sensor to light. To improve the performance in darker environments, a higher ISO value is required. On the other hand, a lower ISO value is needed when in bright conditions. (The ISO setting is only available when the camera is in the M Manual mode).
Pictures taken with higher ISO will generally have more noise than those taken with lower ISO.
The options of ISO include automatic, 64, 100, 200, 400, 800 and 1600.
Exposure Compensation

EV adjustment can also be changed in Movie mode.
