ISO is the term used to describe the sensitivity of film to light, defined by the International Organization for Standardization (ISO).
With film cameras, this ISO rating was used when describing different types of photographic film, from 100 ISO (low sensitivity to light) to 1600 ISO (high sensitivity to light). With digital cameras, the ISO rating has remained, and now refers to the sensitivity of the camera sensor to light.

100 ISO, the standard setting
Most digital cameras come with the ISO set to 100 as standard. This means that the camera will record the best image possible with the least amount of digital noise, at the potential cost of a slower shutter speed. In other words the shutter has to remain open for longer to capture the photo as the camera sensor is at its least sensitive to light.
