Shooting Using the Mode Dial 96
See Functions Available in Each Shooting Mode (p. 270).
The aperture adjusts the amount of light entering through the lens.
When you set the aperture, 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 the aperture) 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.
About Safety Shift
If you set [Safety Shift] to [On] (p. 49) in the
menu and press the
shutter button halfway, the camera automatically changes the shutter
speed or aperture value to obtain the correct exposure if necessary.
The safety shift function does not work when the flash is on.
