Advanced shooting functions
Noise reduction
When shooting in dark places, shutter speeds become slower as there is
less light focused on the CCD. During long exposures, signals are
generated by parts of the CCD where no light is focused and are recorded
on the image as noise. When [NOISE REDUCTION] is set to [ON], the
camera automatically reduces the noise to produce clearer images.
ON Noise is reduced. Shooting time is twice as
long as usual. Noise reduction can only be
used when using slow shutter speeds.
OFF Noise is not reduced. Noise may be
conspicuous with slow shutter speeds.
The purpose of these pictures is to illustrate the effects of noise reduction. They are
not actual pictures.
