Adjusting the Camera Settings in Shooting Mode M ISO Sensitivity Sensitivity is a measure of the camera's response to light. The higher the sensitivity, the less light is needed to expose an image. Although high ISO sensitivity settings are suited to pictures of moving subjects or those taken under dim lighting, high sensitivity settings are often associated with "noise"- randomly spaced, brightly colored pixels - concentrated in dark portions of images. More on Shooting 9 Tap X in shooting mode to adjust the setting. The following options are available. a Auto (default setting) Sensitivity is ISO 80 when there is sufficient lighting; the camera compensates by raising sensitivity to a maximum of ISO 800 when lighting is poor. Z Fixed range auto Choose the range in which the camera automatically adjusts ISO sensitivity, from y ISO 80-200 or z ISO 80-400. The camera will not raise sensitivity beyond the maximum value in the selected range. Set the maximum value for ISO sensitivity for effective control over the amount of "grain" that appears in images. 80, 100, 200, 400, 800, 1600, 3200, 6400 Sensitivity is locked at the specified value. When the ISO sensitivity setting is set to any option other than a Auto, motion detection (A 34) is disabled. B Note on ISO Setting There may be functions with which this setting cannot be enabled.
