How to use ISO
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.
