How quickly, CCD or CMOS sensor in digital cameras is sensitized or reacted quickly to the touch of light is determined by the ISO number. Low ISO Rating means more light is needed for less sensitive ie accurate exposure. The opposite of the high ISO rating is the opposite. Generally ISO 100 - ISO 400 usage is more.

The higher the ISO rating the camera will be able to make less light photos. In addition to taking quick shutter speed shots, the ISO rating is even higher. The negative aspect of the High ISO Rating is that the photo creates a 'noise'.
