E Iso Sensitivity - Nikon COOLPIX P80 User Manual

Shooting Options: The Shooting Menu

E ISO Sensitivity

Sensitivity is a measure of how quickly the camera reacts to light. The higher the
sensitivity, the less light needed to make an exposure. Although a high ISO rating
is suited for shooting pictures of subjects in action or in poor lighting, high
sensitivity is often associated with "noise" - randomly spaced, brightly colored
pixels concentrated in dark parts of the image.
Auto (default setting)
Sensitivity is ISO 64 under normal conditions; when lighting is poor and the flash is
off, the camera compensates by raising sensitivity to a maximum of ISO 800.
In M mode, sensitivity will be locked at ISO 64.
High ISO sensitivity auto
The ISO sensitivity is set automatically within the range of ISO 64 to 1600 according
to the brightness of the subject.
If High ISO sensitivity auto is set when M is selected with the mode dial, the ISO
sensitivity is fixed to 64.
Fixed range auto
Choose the range in which the camera automatically adjusts ISO sensitivity, in P, S,
and A modes, from ISO 64-100 (default setting), ISO 64-200, or ISO 64-400. The
camera will not raise sensitivity beyond the maximum value in the selected range
for effective control over the amount of "grain" that appears in images.
In M mode, sensitivity will be locked at ISO 64.
64, 100, 200, 400, 800, 1600, 2000, 3200, 6400
Sensitivity will be locked at the specified value.
At the settings other than Auto, the current setting is displayed in the monitor
(A 6). If Auto is selected and the sensitivity is raised above ISO 64, the E icon
will be displayed (A 32). When High ISO sensitivity auto is selected, V is
displayed. When Fixed range auto is selected, U and the maximum ISO
sensitivity value are displayed.

Notes on ISO 3200 and 6400
• When 3200 or 6400 is selected for ISO sensitivity, a X icon will appear on the ISO sensitivity
value. In addition, the image size will display in red during shooting.
• When ISO sensitivity is set to 3200 or 6400, Image size cannot be set to M 3648×2736,
E 3264×2448, D 2592×1944, I 3648×2432, G 3584×2016, and H 2736×2736. At these
image size settings, selecting 3200 or 6400 for ISO sensitivity automatically switches the Image
size setting to C 2048×1536. When any option other than 3200 or 6400 is next selected for
ISO sensitivity, the original image size setting is restored.
• At an ISO sensitivity setting of 3200 or 6400, the Multi-shot 16 (A 98) option of the
continuous shooting mode is not available. At a Continuous setting of Multi-shot 16, selecting
3200 or 6400 for ISO sensitivity switches the Continuous setting to Single. The Continuous
setting does not change even when ISO sensitivity is set to options other than 3200 or 6400.
