      ❯❯ On/Off switch: Okay, you probably already figured this one out. What you may not know is that by default, the camera automatically shuts itself off after one minute of inactivity to save battery power. To wake up the camera, press the shutter button halfway or press the Menu, Info, or Playback button. You can adjust the auto shutdown timing via the Auto Power Off option on Setup Menu 2.

      ❯❯ Mode dial: Through this dial, you select an exposure mode, which determines whether the camera operates in fully automatic, semi-automatic, or manual exposure mode. To adjust the setting, press and hold the unlock button in the center of the dial as you rotate the dial. Chapter 2 introduces you to the various exposure modes.

      ❯❯ Hot shoe: The hot shoe is a metal bracket on which you can affix an external flash (or other hot shoe accessory). It’s called a hot shoe because it’s wired to communicate back and forth from the camera using electrical signals. Don’t go poking around the hot shoe: the flash-sync contacts (the little round metal posts) need to be clean and free of debris to work properly.

      ❯❯ Microphone: These two clusters of holes lead to the stereo microphone that picks up sound when you record movies.

      ❯❯ AF Area Selection button: This button enables you to change the AF Area Selection setting, an autofocus feature that we describe in Chapter 8.

      ❯❯ Drive button: This button switches between the various shutter-release (drive) modes, such as single frame, self-timer, or high-speed continuous. See Chapter 2 for more information.

      ❯❯ ISO button: Press this button to access the ISO speed setting, which determines how sensitive the camera is to light. Chapter 7 details this critical exposure setting.

      ❯❯ Metering mode button: Yup, you guessed it: This button enables you to choose the camera's metering mode, which determines which part of the scene the camera uses to set exposure. Chapter 7 has details.

      ❯❯ AF button: This button is related to the AF mode setting, which determines when the camera locks focus when you use autofocusing. See Chapter 8 for the lowdown.

      ❯❯ Main dial: You use this dial, labeled in the figure, when selecting many camera settings. In fact, this dial plays such an important role that you’d think it might have a more auspicious name, like The Really Useful Dial, but Main dial it is.

      ❯❯ Shutter release button: You probably already understand the function of this button, too. But what you may not realize is that when you use autofocus and autoexposure, you need to use a two-stage process when taking a picture: Press the shutter button halfway, pause to let the camera set focus and exposure, and then press the rest of the way to capture the image. You’d be surprised how many people mess up their pictures because they press that button with one quick jab, denying the camera the time it needs to set focus and exposure.

      ❯❯ LCD panel illumination button: This button illuminates the top LCD panel with an amber backlight.

      ❯❯ Focal plane mark: Should you need to know the exact distance between your subject and the camera, the focal plane indicator is key. This mark indicates the plane at which light coming through the lens is focused onto the image sensor. Basing your measurement on this mark produces a more accurate camera-to-subject distance than using the end of the lens or some other external point on the camera body as your reference point.
