Press and hold the shutter button halfway down to set focus and exposure

When the camera establishes focus, it emits a tiny beep and displays a green focus light in the top-right corner of the display, as shown in Figure 3-2. In addition, a green square appears briefly to indicate the focus target — the area of the frame the camera used to establish focus. Typically, the camera locks onto the closest object in the scene, as it did for the example photo in the figure.

Face Detection is enabled in iAuto mode, so if there are people in the scene, you also see the white face-detection frame on the monitor before and after the green focus target lights. See Chapter 2 for details about Face Detection. (You can't disable the feature in iAuto mode.) If the light is such that the camera can't select optimal exposure settings, the aperture and shutter speed values blink. I labeled these values in Figure 3-2; see Chapter 6 for a complete explanation. In dim lighting, try adding flash; in very bright light, you may need to move the subject into a shaded area.

Figure 3-1: The iAuto mode lets you enjoy fully automatic photography or take more control through the Live Guide feature.
