Using the Flash

BShooting When Lighting is Poor and When the Flash is Disabled (W)

•Use of a tripod is recommended to stabilize the camera during shooting and avoid the effects of camera shake. Set Vibration reduction (A 125) in the setup menu (A 116) to Off when using a tripod to stabilize the camera during shooting.

•The Eindicator is displayed when the camera automatically increases sensitivity. Pictures taken when Eis displayed may be slightly mottled.

•When Eis displayed and higher sensitivity is applied, noise reduction may be automatically applied as pictures are recorded. This will result in increased recording times.

BNote on Using the Flash

Reflections from dust particles in the air may appear as bright spots in pictures. To reduce these reflections, set the flash to W (off).

CThe Flash Lamp

The flash lamp indicates the flash status when the shutter-release button is pressed halfway down.

•	On	: Flash will fire when picture is shot.
•	Blinks	: Flash is charging. Wait a few seconds and try again.
•	Off	: Flash will not fire when picture is shot.

If the battery is low, the monitor display will turn off, and remain off, until the flash is fully charged.

CFlash Setting

The default flash mode setting varies with shooting mode.

•A (auto): U auto.

•Scene mode: setting varies for different scene modes (A 38-44).

•F(smart portrait) mode: set to Woff (when Blink Proof is on), Uauto (when Blink Proof is off) (A53)

•Flash cannot be used simultaneously with certain features (A 109).

•s (subject tracking): W off

The flash mode setting applied in A (auto) mode is stored in the camera’s memory even after the camera is turned off, and reapplied the next time A (auto) mode is selected.

Basic Photography and Playback: Auto Mode

CRed-eye Reduction

This camera uses Advanced Red-eye Reduction (“In-Camera Red-Eye Fix”).

Pre-flashes are fired repeatedly at low intensity before the main flash, reducing the red-eye effect. If the camera detects “red-eye” when a picture is taken, Nikon’s own In-Camera Red-Eye Fix processes the image before it is recorded.

Note the following when taking pictures:

• Because pre-flashes are fired, there is a slight lag between when the shutter-release button is pressed and when the picture is shot. This mode is not recommended when a quick shutter response is required.

• The time required to save the picture increases slightly.

• Advanced red-eye reduction may not produce the desired results in some situations.

• In extremely rare instances, areas not subject to red-eye may be affected by advanced red-eye reduction processing; in these cases, choose another mode and try again.
