Taking Photographs-Sensitivity (ISO Equivalency) Sensitivity (ISO Equivalency) Reacting Faster to Light "Sensitivity" is the digital equivalent of film speed. The higher the sensitivity, the less light needed to make an exposure, allowing higher shutter speeds or smaller apertures. Sensitivity can be set between values roughly equivalent to ISO 200 and ISO 1600 in steps equivalent to 1/3 EV. Higher values of HI-1 (approximately equivalent to ISO 3200) and HI-2 (approximately equivalent to ISO 6400) are also available for situations in which high sensitivity is a priority. Sensitivity can be adjusted using the ISO option in the shooting menu or by pressing the ISO button and rotating the main command dial.

Photos taken at settings of HI-1 and HI-2 will likely contain appreciable amounts of noise. Use only to capture natural lighting under low light conditions or when a fast shutter speed is required to prevent blurring. Nikon recommends that image sharpening ( 65) be turned off at these settings to avoid heightening the effects of noise. 48
