Troubleshooting
The subject is overexposed
because the surroundings
are too dark.
Set the exposure compensation to a
negative (–) setting (p. 49).
Use the spot metering functions
(p. 48).
Too much light is shining
directly into the camera, or
is being reflected off the
subject.
Change the shooting angle.
Flash is set to on.
Set the flash to
(Flash off)
(
Basic Guide
p. 12).
Image contains noise.
ISO speed is too high.
Higher ISO speeds and
(High
ISO Auto) setting may increase
image noise. For higher image
quality, use as low an ISO speed
as possible (p. 53).
In
,
,
and
,
modes in the
mode, the ISO
speed increases and noise can
appear.
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 Av mode.
This is a phenomenon that occurs
with digital cameras and does not
constitute a malfunction.
