These two pictures are depth of field examples I use in photo class.

On the left my lens aperture was F16 and on the right F4. By choosing your aperture in the aperture priority or manual mode, you can control your depth of focus.

Two more examples of aperture control. On the left I have a shot in Program, but on the right I used F4 in aperture priority mode. You could also create the shot on the right with the portrait setting in the scene mode. By controlling your depth of field, you can direct the viewer’s eye to what is important in your photograph.
