Shooting Using the Mode Dial 83
See Functions Available in Each Shooting Mode (p. 207) .
When you set the shutter speed, the camera automatically selects an
aperture value to match the brightness of the subject. 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 is shown in red, the image is
underexposed (insufficient light) or overexposed (too much
light). Use the or button to adjust the shutter speed until
the aperture value shows in white.
The nature of CCDs 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. (However, a certain amount of
processing time may be required before the next image can be
shot.)
