This is a phenomenon that occurs
with digital cameras and does not
constitute a malfunction.
Set the [Red-Eye] function to [On]
and shoot (p. 35). 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.
You can correct red eyes in images
using the Red-Eye Correction
function (p. 85).
To enhance the continuous shooting
performance, you are recommended
to format (Low Level Format) the
memory card in the camera after you
save all its images to your computer
(p. 29).
Use a memory card formatted in your
camera (p. 29).
