Sleep and Shutoff Modes Continued

■ Shutoff mode usually takes over after 5 or 10 minutes of inactivity, turning the camera completely off. When you want to take pictures, you'll have to turn it on again.

While we don't recommend it for most users, many cameras allow you to turn off both the sleep and shutoff modes, so you're always instantly ready to shoot—that is, if you have any battery power left after keeping the camera on continuously when it should have gone to sleep or been turned off.

Figure 3-2: This Canon PowerShot A310 has a so-called clamshell design, that is, a sliding cover over the lens. Sliding the cover to reveal the lens turns on the camera. In this picture, the cover is open and the camera is on, though the lens hasn't yet fully opened.
