To blur the background or to make everything near and far look sharp,
set the Mode Dial to <f> (Aperture-priority AE) to adjust the depth of
field (range of acceptable focus).
* <f> stands for Aperture value (the size of the lens diaphragm opening).

Set the desired aperture.

The higher the f/number, the wider
the depth of field where sharper focus
is obtained in both the foreground
and background.
Turning the <6> dial clockwise sets
a higher f/number (smaller aperture
opening), and turning it
counterclockwise sets a lower
f/number (larger aperture opening).
Take the picture.

When you focus and press the
shutter button completely, the picture
