BASIC IMAGE RECORDING
65
IMPORTANT!
• The flash unit of this camera fires a number of times
when you record an image. The initial flashes are
pre-flashes, which the camera uses to obtain
information that it uses for exposure settings. The
final flash is for recording. Make sure that you keep
the camera still until the shutter releases.
• Using the flash while “Auto” is selected for the ISO
Sensitivity setting increases sensitivity, which can
cause large amounts of digital noise to appear in the
image. You can reduce digital noise by using a lower
ISO Sensitivity setting. Note, however, that this also
has the effect of shortening the flash range (the
range that is covered by the light from the flash)
(page 125).
■ Flash On
Select (Flash On) as the flash mode when backlighting
causes your subject to appear dark, even though there is
enough light to keep the flash from firing automatically.
This will cause the flash to fire and illuminate your subject
whenever you press the shutter button (daylight synchro
flash).
■ About Red-eye Reduction
Using the flash to record at night or in a dimly lit room can
cause red spots inside the eyes of people who are in the
image. This happens because the light from the flash
reflects off of the retina of the eye.
IMPORTANT!
Note the following important points when using red-
eye reduction.
• Red-eye reduction does not work unless the people
in the image are looking directly at the camera during
the pre-flash. Before pressing the shutter button, call
out to the subjects so they all look at the camera
while the pre-flash operation is performed.
• Red-eye reduction may not work very well if the
subjects are located far away from the camera.
