Shooting
When you use flash photography at higher ISO speeds, the
chances of white streaks appearing in the image increase
the closer you approach to the subject.
Since a slow shutter speed is selected in dark places when
the flash is set to Off or Slow-Synchro, take care to avoid
blurring the image.
- Shooting in
Mode
Be careful to hold the camera still to avoid camera shake.
- Shooting in
or
Mode
Fix the camera to a tripod to shoot in these modes since
the shutter speed will be slower than in the
mode. If
an image is dark in
mode, reshooting it in mode
will make it brighter.
The flash can be fired when the upper indicator lights a steady
orange after pressing the shutter button halfway (The flash
will not fire when it is set to Off).
The flash may take up to approximately 10 seconds to charge.
The recharging time will vary with such factors as the shooting
conditions and battery charge.
Shots cannot be taken while
the flash is charging.
The flash fires twice. The main flash follows a preparatory pre-
flash. The exposure reading obtained from the subject with the
pre-flash is used to set the optimal flash intensity for the main
flash, which is used to capture the image.
Red-Eye Reduction
Light reflecting back from eyes can make them appear red when
the flash is used in dark areas. Under these conditions, use the red-
eye reduction mode. For this mode to be effective, the subject
must be looking right at the red-eye reduction lamp. Try asking
them to look directly at the lamp. Even better results can be
obtained by shooting with the lens set to a wide angle, increasing
the lighting in indoor settings or approaching closer to the subject.
The shutter will not activate for approximately 1 second after
the red-eye reduction lamp fires in order to improve the
effect. If you want a more immediate shutter response, set the
flash to
