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.
• If the aperture value shows in red, the
image is underexposed (insufficient light) or
overexposed (too much light). Adjust the
shutter speed using the ... or .. button until
the aperture value display turns to white.
• 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.
