Troubleshooting
The subject is
overexposed because the
surroundings are too
dark.
Set the exposure compensation to
a negative (–) setting (p. 44).
Use the AE lock or spot metering
function (pp. 42, 44).
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. 14).
Image contains noise.
ISO speed is too high.
Higher ISO speeds or
may
increase image noise. For higher
image quality, use as low an ISO
speed as possible (p. 52).
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 at wide
angle settings.
This is a phenomenon that occurs
with digital cameras and does not
constitute a malfunction.
