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.

is set to Off or Slow Synchro, take care to avoid blurring the image.

in , , , or mode
Be careful to hold the camera still to avoid camera shake.

Fix the camera to a tripod to shoot in these modes since the
shutter speed will be slower than in the
mode.
• The flash can be fired when the indicator lights a steady orange after

• 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.
• When using the flash for standard photography, be sure to shoot
from a distance of at least 30 cm (12 in.) away from your subject.
Red-Eye Reduction

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
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 (excluding
when using the quick shot function). If you want a more immediate
shutter response, set the flash to
