If the aperture value is shown in red, the image is
underexposed (insufficient light) or overexposed (too much
light). Use the control dial to adjust the shutter speed until
the aperture value shows in white.
z
The nature of CCD image sensors is such that noise in the
recorded image increases at slow shutter speeds. This
camera, however, applies special processing to images
shot when the shutter speed is 1.3 seconds or slower to
eliminate the noise, thereby producing high-quality images.
(However, a certain amount of processing time may be
required before the next image can be shot.)
z
The aperture value and shutter speed change according to
the zoom state as follows
z
The fastest shutter speed for flash synchronization is 1/500
second. The camera automatically resets the shutter speed
to 1/500 second if a faster speed is selected.

The following shutter speeds can be set. 1/160 indicates 1/160
second. Also, 0"3 indicates 0.3 second and 2" indicates 2 seconds.

You can change the automatically selected combinations of
shutter speeds and aperture values without altering the
exposure (p. 69).
