Shutter Speed - Canon POWERSHOT PRO1 User Manual

2
Turn the main dial and select a

shutter speed.

3
Shoot the image.
The correct exposure has been set if the
shutter speed and aperture value show in
white on the LCD monitor (or in the
viewfinder).
If the aperture value is shown in red on
the LCD monitor (or in the viewfinder),
the image is underexposed (insufficient
light) or overexposed (too much light).
Adjust the shutter speed using the main
dial until the aperture value display turns
to white.
If you set [Safety Shift] to [On] in the Rec.
menu, the shutter speed will shift to the
correct speed automatically. (Safety Shift
function (p. 86))
If you adjust the zoom after you set the
shutter speed, the aperture value is
sometimes changed according to the
zoom position.
You can change the automatically
selected combinations of shutter speeds
and aperture values without altering the
exposure (p. 105).
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.
