other. Then drag both toward the center of the screen. To pinch out, start in the center of the screen and swipe both fingers outward. Pinching is how you zoom in and out of pictures during playback.

      tip You can customize two aspects of touchscreen behavior:

❯❯ Adjust (or disable) the touchscreen response: You can choose from three settings, accessed via the Touch Control option, found on Setup Menu 3 and shown in Figure 1-16. Standard is the default, setting the screen to respond to a “normal” amount of pressure. Don’t ask how the Powers That Be decided what that pressure level is – just know that if your normal pressure doesn’t evoke a response, you can change the setting from Standard to Sensitive. Choose Disable to make the touchscreen totally inactive.

      ❯❯ Silence the touchscreen: By default, the touchscreen emits a tiny “boop” with every tap. If you find that annoying, choose the Beep option, found just beneath the Touch Control option on Setup Menu 3. The option that keeps the boop silent is Touch to Silence – silence indicated by a little speaker with a slash through it. The Disable setting turns off both touchscreen sounds and the beep the camera emits when focus is achieved.

      tip_white CARING FOR THE CAMERA MONITOR

      To keep the monitor in good working order, follow these precautions:

      ● Don’t use force when adjusting the monitor position. Although the monitor assembly is sturdy, treat it with respect as you adjust the screen position. The monitor twists only in certain directions, and it’s easy to forget which way it’s supposed to move. So if you feel resistance, don’t force things – you could break the monitor. Instead, rely on that feeling of resistance to remind you to turn the screen the other way.

      ● Use only your finger to perform touchscreen functions. Use the touchscreen, use the fleshy part of your fingertip (not the nail or any other sharp object), and be sure your fingers are dry because the screen may not respond if it gets wet.

      ● Don’t apply a screen protector. Canon also advises against putting a protective cover over the monitor, such as the kind people adhere to their smartphones. Doing so can reduce the monitor’s responsiveness to your touch.

      ● Watch the crunch factor. Before positioning the monitor back into the camera (whether face in or face out), use a lens brush or soft cloth to clean the monitor housing so there’s nothing on it that could damage the monitor.

      ● Clean smart. To clean the screen, use only the special cloths and cleaning solutions made for this purpose. (You can find them in any camera store.) Do not use paper products such as paper towels because they can contain wood fibers that can scratch the monitor. And never use a can of compressed air to blow dust off the camera – the air is cold and can crack the monitor.

      Viewing Camera Settings

      Your camera offers several displays that present the current picture-taking settings. The next sections explain the displays that are available during viewfinder photography. See the later section “Switching to Live View Mode” for information about displaying similar data when you use Live View, the feature that enables you to compose photos on the monitor instead of through the viewfinder.

      remember For still photography, you can use either the viewfinder or Live View screen to compose your shots. But when you set the camera to Movie mode, you’re limited to Live View.

Displaying the Quick Control screen

Shown in Figure 1-17, the Quick Control screen appears on the monitor when the camera is in shooting mode – that is, you’re not viewing menus, checking out your pictures in playback mode, and so on. The screen displays different data depending on your exposure mode and whether features such as flash are enabled. The left side of Figure 1-17 shows the screen as it appears in Auto exposure mode; the right side, Tv mode (shutter-priority autoexposure).

       FIGURE 1-17: The data displayed on the Quick Control screen depends on your exposure mode.

      Here are the keys to taking advantage of this screen:

      ❯❯ Displaying and hiding the Quick Control screen: By default, the screen appears automatically when you turn on the camera and turns off if no camera operations are performed for 30 seconds. You can turn the display on again by pressing the shutter button halfway and then releasing it. To turn off the display before the automatic shutoff occurs, press the DISP button (top of the camera, just behind the Main dial).

      tip You can adjust the timing of the automatic shutdown of this screen and others by selecting the Auto Power Off option from Setup Menu 2. I provide the details near the end of this chapter, in the section devoted to that menu.

      ❯❯ tip Curved arrows bordering a setting mean that you can rotate the Main dial to adjust that setting. For example, in the Tv exposure mode, the shutter speed is bordered by the arrows, as shown on the right in Figure 1-17, indicating that rotating the Main dial changes that setting.

      ❯❯ Keep an eye on the battery symbol and the shots remaining value, both labeled in Figure 1-17. A full battery like the one in the figure means that the battery is charged; as it runs out of power, bars disappear from the symbol. The shots remaining value indicates how many more pictures will fit in the free space available on your memory card. This value depends in large part on the Image Quality setting, which determines the resolution (pixel count) and file type (Raw or JPEG). If those terms are new to you, the next chapter explains them.

❯❯ You can replace the Quick Control screen with an electronic level by pressing the Info button. This feature is helpful when you use a tripod and want to ensure the camera is level to the horizon. When the horizontal line appears green, as shown in Figure 1-18, you’re good to go. Press Info again to return to the Quick Control screen. (The Info button resides just to the left of the viewfinder.)

Decoding viewfinder data

A limited assortment of shooting data, such as the shutter speed and f-stop, appears at the bottom of the viewfinder, as shown in Figure 1-19. How much data appears depends on your exposure mode and what picture settings are currently in force; the figure shows the basics. Upcoming chapters explain the entire cadre of settings data.

      In the framing area of the viewfinder, you may see marks that indicate the portion of the screen that contains autofocusing points. (The appearance of the autofocus markings depend on your autofocus settings, which you can explore in Chapter 5.) In the
