Camera Sensitivity - ISO

3 1

Five settings can be selected for camera sensitivity: Auto, 64, 100, 200, 400, and 800; the numerical values are based on an ISO equivalent. ISO is the standard used to indicate film sensitivity: the higher the number, the more sensitive the film.

Turn the function dial to the ISO position (1). Press the function button in the center of the dial (2). Turn the front or rear control dials to change the camera sensi- tivity (3). Press the shutter-release button partway down

The auto setting automatically adjusts the camera sensitivity to the light conditions between ISO 64 and 200. When any other setting than auto is used, “ISO” will appear on the data panel, and “ISO” and the set value will be displayed on the monitors.

Photographers can select a specific sensitivity setting. Like grain in silver-halide film that increases with speed, noise increases with sensitivity in digital imaging; an ISO setting of 64 will have the least noise and 800 will have the most.

A change in ISO also affects the flash and shutter-speed range; the higher the ISO, the greater the range. See the next page for more on the flash range, and page 55 for the shutter-speed range.

As the ISO value doubles, the camera sensitivity doubles; changing the ISO between 100 and 200, 200 and 400, or 400 and 800 changes the camera sensitivity by one stop or 1 Ev (p. 111). A change between 100 and 800 changes the camera sensitivity by a factor of 8 or three stops. High ISO set- tings (400, 800) can allow the photographer to hand hold the camera in low-light conditions without the need of a flash.
