ISO

ISO is the unit for the light sensitivity of the camera's storage medium. For analogue cameras, this refers to the film speed, for digital cameras to the sensor sensitivity.

The higher the ISO value, the more light-sensitive the sensor or film is, i.e. the less light is required. This allows pictures to be taken in the evening and even at night.

Disadvantages of a high ISO setting: Reduction in image quality in the form of blurring and noise.
