Shooting the Subject and Background
Both in Focus
Select a large aperture value such as f8 to have both your subject and the background
scenery in focus.
Set the mode dial to A (Aperture priority mode) and
then select a large aperture value by turning the main
dial.
Note
• The number for the aperture value is inversely proportional
to the aperture diameter. Selecting a large number (11 for
example) decreases the diameter of the aperture,
lengthens the depth of field, and brings the background
into focus.
Setting the Aperture Value (
➞ 72)
However, selecting a large aperture value in low light
will slow down the shutter speed, causing the picture
to blur as a result of camera shake. Under these
conditions, try to steady the camera as much as
possible by leaning against the side of a building, a
tree or a lamp post, or mount the camera on a tripod.
