Iso Sensitivity - Nikon D5200 Reference Manual

ISO Sensitivity

"ISO sensitivity" is the digital equivalent of film speed. The higher the ISO sensitivity,
the less light needed to make an exposure, allowing higher shutter speeds or smaller
apertures, but the more likely the image is to be affected by noise (randomly-spaced
bright pixels, fog, or lines; noise is particularly likely at settings between Hi 0.3
(equivalent to ISO 8000) and Hi 2 (equivalent to ISO 25600)). Choosing Auto allows
the camera to set ISO sensitivity automatically in response to lighting conditions.
