methods to obtain the correct exposure and
make them appear in white.
• Use the flash
• Change the ISO speed setting
• Change the light metering mode

Setting the Shutter Speed
When you set the shutter speed in the shutter-
speed priority AE mode, the camera automatically
selects an aperture value to match the brightness.
Faster shutter speeds allow you to catch an
instantaneous image of a moving subject while
slower speeds create a flowing effect and allow
you to shoot without a flash in dark areas.
z If the aperture value shows in red, the
image is underexposed (insufficient
light) or overexposed (too much light).
Adjust the shutter speed using the left or
right button until the aperture value
display turns to 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 at shutter
speeds slower than 1.3 seconds to
eliminate the noise, thereby producing
high-quality images. Nevertheless, a
certain amount of processing time may
be required before the next image can
be shot.
