White dots appear on the image.
Light from the flash has
reflected off dust particles
or insects in the air. This is
particularly noticeable
when shooting using the
wide angle or when you
increase the aperture
value in the aperture
priority mode.
Eyes appear red.
Light is reflected back
from the eyes when the
flash is used in dark
areas.
Continuous shooting slows down.
The memory card's
performance has dropped.
This is a phenomenon that occurs
with digital cameras and does not
constitute a malfunction.
Shoot with [Red-Eye Lamp] in the
[Flash Settings] menu set to [On]
(p. 86). 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.
If you set the [Red Eye Corr.] in the
[Flash Settings] to [On], the camera
will automatically correct red eyes
while shooting and record the image
to the card (p. 86).
You can correct red eyes in recorded
images using the [Red-Eye
Correction] (p. 122).
To enhance the continuous shooting
performance, you are recommended
to low level format the memory card in
the camera after you save all its
images to your computer (p. 141).
