Setting the Aperture
When you set the aperture in the aperture-priority AE mode, the
camera automatically selects a shutter speed to match the
brightness.
Selecting a lower aperture value (opening the aperture) allows you
to blur the background and create a beautiful portrait. A higher
aperture value (closing it) brings the entire range from foreground to
background into focus. The larger the aperture value, the greater the
range of the image brought into clear focus.
1
Turn the mode dial to Av.
z The aperture value will show on the display
panel. It will also be displayed on the LCD
Monitor if the monitor is on.
2
Turn the main dial and select an
aperture value.
3
Shoot the image.
z The correct exposure has been set if the
shutter speed and aperture value show in
white on the LCD monitor.
z If the shutter speed is shown in red on the
LCD monitor, the image is underexposed
(insufficient light) or overexposed (too
much light). Adjust the aperture value
using the main dial until the shutter speed
display turns to white.
If you set [Safety Shift] to [On] in the Rec.
menu, the aperture value will shift to the
correct value automatically (Safety Shift
function (p. 86)).
z You can change the automatically
selected combinations of shutter speeds
and aperture values without altering the
exposure (p. 106).
