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.
1 Use the
W
or
X
button to select the shutter speed,
then shoot.
Shooting Mode
zIf the aperture value is shown in red, the image is
underexposed (insufficient light) or overexposed (too much
light). Use the W or X button to adjust the shutter speed until
the aperture value shows in white.
zThe 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).
zThe aperture value and shutter speed change according to
the zoom state as follows.
zThe 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.
