Basic Shooting
This chapter explains how to use the Basic Zone modes
on the Mode Dial for best results.
With Basic Zone modes, all you do is point and shoot and the
camera sets everything automatically (p.276). Also, to prevent
botched pictures due to mistaken operations, major shooting
settings cannot be changed in the fully-automatic modes.
