Setting the Shutter Speed

PowerShot A540
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
until the aperture value shows in 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.
(However, a certain amount of processing time may be
required before the next image can be shot.)
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.
