When using a zoom lens, use the wide-angle end. This will have
objects near and far in focus, better than at the telephoto end. It also
adds breadth to landscapes.
Shooting night scenes.

mode is also good for night scenes. For night
scenes, use a tripod to prevent camera
shake. If you want to photograph a person
against a night scene, set the Mode Dial to
<6> and use a tripod. (p.53)
