Photographs taken at slow shutter speeds are prone to blurring. If 190 sensitivity is raised
above the base setting of ISO 200 equivalent, the same exposures can be achieved at faster
shutter speeds, preventing blur. 150 sensitivity can be set to values between 190 200 and
190 1600 in steps of 1EV, with a further high sensitivity setting of HI 1 available for an 190
equivalent of roughly .5200. A_ (auto) and Digital Vari Program modes also offer an Auto
setting that allows the camera to automatically raise sensitivity when lighting is poor or
lower sensitivity when lighting is bright. Rotating the mode dial from P,S,A,or M to A_oor a
Digital Vari Program mode automatically restores the default ISO sensitivity of Auto.
_ Sensitivity
150 sensitivity is the digital equivalent of film speed. The higher the 150 sensitivity, the less light
needed to make an exposure, allowing higher shutter speeds or smaller apertures. Just as higher
speed films tend to be "grainy/' pictures taken at high ISOsensitivitiesare prone to mottling. Photos
taken at an ISOsensitivity of HI 1 are automatically processed to reduce noise, resulting in increased
recording times.
