53Changing Shooting SettingsISO SensitivitySelect ISO sensitivity from the Quick settings display to adjust the setting (A 48).Photographs taken at slow shutter speeds are prone to blurring. If ISO sensitivity is raisedabove the base setting of ISO 100, the same exposures can be achieved at faster shutterspeeds, preventing blur. ISO sensitivity can be set to values between ISO 100 and ISO 1600in steps of 1EV, with a further high sensitivity setting of Hi 1 available for an ISO equivalentof approx. 3200.Digital Vari-Program modes also offer an Auto setting that allows the camera toautomatically raise sensitivity when lighting is poor or lower sensitivity when lighting isbright.B High Sensitivity Setting of Hi 1Photographs taken at a sensitivity setting of Hi 1 are prone to be grainy and exhibit mottling.C ISO Sensitivity SettingRotating the mode dial from a, b, c, or d to a Digital Vari-Program mode automatically restoresthe default ISO sensitivity of Auto.C ISO AutoUse Custom Setting 10 (ISO auto; A 111) to enable automatic ISO sensitivity control in a, b, c,and d modes. When Hi 1 is selected, automatic ISO sensitivity control is disabled.C More InformationFor more information about reduce noise at high sensitivities, see Noise reduction in the shootingmenu (A 108).D SensitivityISO sensitivity is the digital equivalent of film speed. The higher the ISO sensitivity, the less lightneeded to make an exposure, allowing higher shutter speeds or smaller apertures. Just as higherspeed films tend to be “grainy,” photographs taken at high ISO sensitivities are prone to mottling.E ISO SensitivityISO sensitivity can also be set using the ISO sensitivity option in the shooting menu (A 100).F 11 — F/G Button (A 112)ISO sensitivity can also be set using the command dial.e, f, g, h,i, j, k, l Auto (default setting), 100–1600, Hi 1a, b, c, d 100 (default setting)–1600, Hi 1
