Viewing Camera Settings
Your camera offers several displays that show 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 take advantage of Live View, the feature that enables you to compose photos on the monitor instead of using the viewfinder.
Displaying the Quick Control screen
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 1-21 shows the screen as it appears in Scene Intelligent Auto exposure mode; the right side, Tv mode (shutter-priority autoexposure).
FIGURE 1-21: 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 goes to sleep if no camera operations are performed for 30 seconds. You can wake up the display by pressing the shutter button halfway and then releasing it. If you want to turn off the display before the automatic shutoff occurs, press the DISP button (top of the camera, just behind the Main dial). 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.
Keep an eye on the battery symbol and the shots remaining value, both labeled in Figure 1-21. 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, shown in Figure 1-22. 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 1-22, you’re good to go. By default, you need to press the Info button twice to shift from the Quick Control screen to the level. Your first press turns off the screen, and the second press brings up the level. Press Info again to return to the Quick Control screen. Again, which screens appear when you press the Info button depends on the Info Button Display Options setting, found on Setup Menu 4. You can find details on this option in the section “Setup Menu 4,” found near the end of this chapter.

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 1-23. 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 data.
FIGURE 1-23: The default viewfinder display (left) can be customized to include a grid, electronic level, and flicker warning (right).
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 left screen in the figure, the four black brackets represent the autofocusing area.
Here’s how to display and customize the viewfinder:
Displaying viewfinder data: The markings in the framing area of the viewfinder appear automatically when you first turn on the camera; to display the shooting data, press the shutter button halfway. The display remains active for a few seconds after you release the button, and then the viewfinder display shuts off to save battery power. To wake up the display, press the shutter button halfway and release it.
Adding a level and gridlines to the display: You can display gridlines in the viewfinder, as shown on the right in Figure 1-23, as well as a symbol that represents the electronic level. (When the lines at the sides of the symbol are horizontal, as in the figure, the camera is level.)To hide or display these features, open Setup Menu 4 and choose Viewfinder Display. On the next screen, change the settings from Hide to Show. As you select each option, a preview appears at the bottom of the screen to remind you how enabling each feature affects the display.
Display a flicker-detection warning: When the Mode dial is set to an advanced exposure mode (P, Tv, Av, or M), the Viewfinder Display option on Setup Menu 4 offers a third setting, Flicker Detection. When the camera detects light sources that are blinking, which can mess up exposure and color, the word Flicker! appears in the area labeled in Figure 1-23. The biggest offenders are tubular fluorescent bulbs, which blink on and off so quickly that it’s difficult for the human eye to detect them. When you see this warning, you may want to enable the Anti-flicker Shoot option found on Shooting Menu 4. This feature is covered in Chapter 4.
The number in brackets at the right end of the viewfinder does not represent the shots-remaining value, as it does in the Quick Control screen. Instead, that number — 9, in Figure 1-23 — represents the number of maximum burst frames. This number relates to shooting in the Continuous capture modes, where the camera fires off multiple shots in rapid succession as long as you hold down the shutter button. (Chapter 2 has details.) Although the highest number СКАЧАТЬ
