Not all the information shown in the figure will appear on the screen at the same time. You can adjust the amount of info by pressing the DISP button, exactly as you can with the shooting information screen, as explained in Chapter 2. As you press the DISP button repeatedly, the Live View display cycles among no additional information (basically a blank screen with the magnifying frame and grid—if you've enabled it); a single line of data (shown at the bottom of the screen in the figure); a display with quick settings icons at the left, and an "all of the above" screen that adds an honest-to-gosh real-time histogram (either Brightness or RGB, depending on which you've specified).
I recommend going for the minimalist display most of the time, or, if you can't live without basic data, the version with the line of data at the bottom of the screen. The icon overlays make it difficult to see your subject, and, in any case, you can summon the quick settings icons any time you want to make an adjustment by pressing the Q button. Here's a summary of what you can do with all this screen information. I'll start with the info that's overlaid on the image area of the screen. Seven of them are informational indicators showing the status of some feature:
■ Histogram. Use this display to view the arrangement of tones in your image-to-be, and make exposure adjustments to compensate, as explained under the detailed histogram section at the end of Chapter 4.
■ AF point for contrast detect focusing. A white vertically oriented rectangle appears when you're using AF Live autofocus. The area within the box is used to detect contrast when achieving sharp focus using contrast detection.
■ AF Points for phase detect focusing. When you're using AF Quick, the AF point box changes to a horizontally oriented "magnifying frame" rectangle, and the nine focus points appear, enabling you to choose a focus point manually, as I will describe shortly.
■ AEB/FEB indicators. These appear when you've activated the full screen of information and you are using automatic exposure bracketing and flash exposure bracketing, respectively.
■ Exposure simulation. This indicator appears in three different forms: white, blinking, and gray. When shown in white, the Live View image brightness approximates what you'll get in the final image. Under very bright or very dim conditions, this indicator will blink, indicating that the Live View on the LCD may not closely represent the brightness of the picture you'll take. This indicator is shown in gray if you're using flash or the bulb (manually timed long exposure) setting as a reminder that the view on the LCD may not represent the exposure of the actual picture.
■ AE lock indicator. This icon appears on the full informational screen when you've locked exposure using the AE lock button in the upper-right corner of the back of the camera.
■ Flash ready. This icon appears when your camera's built-in flash is charged and ready to go.
Six of the icons represent settings you can change. They are
■ White Balance. You can select from Auto, Daylight, Shade, Cloudy, Tungsten, White Fluorescent, Flash, or Custom white balances.
■ Picture Style. Choose from among Standard, Portrait, Landscape, Neutral, Faithful, Monochrome, User Def 1, User Def 2, or User Def 3, as described in Chapter 3.
■ Auto Lighting Optimizer. Select Standard, Low, Strong, or Disable, as described in Chapter 3.
■ Image recording quality. You select Large, Medium, and Small Resolution JPEG images, with either Fine or Standard compression, plus RAW or RAW+JPEG.
■ Drive mode. Choose from single shooting, continuous shooting, self-timer/remote control, and self-timer/2 seconds.
■ AF mode. Choose between AF Live, AF Face detection Live, and AF Quick mode. I'll describe these in an upcoming section of this chapter.
To change any of the six settings just described, and shown at the left side of the LCD, just follow these steps.
1. Press the Quick Control button. The settings that can be modified will appear, with the last setting you adjusted highlighted in blue.
2. Select setting. Use the up/down cross keys to highlight the setting you want to change.
3. Make an adjustment. To modify a highlighted setting, rotate the Main Dial until the option you want appears. A line of text appears at the bottom of the screen describing the currently selected option.
4. Exit. Press the Quick Control button again to back out of the Quick Settings screen.
The strip along the bottom of the frame is purely an informational display. Left to right, it shows the currently set shutter speed; f/stop; an exposure scale that can also indicate the automatic exposure bracketing range; an indicator that shows when flash exposure compensation has been activated; the number of shots remaining; current ISO sensitivity setting; whether highlight tone priority has been activated; and a battery status check.
Many of these indicators duplicate what you see in the viewfinder when not using Live View. The most noticeable omission is the focus confirmation indictor that tells you when the image is in sharp focus.
Making Other Settings
Even while using Live View, you can still make other settings using the conventional menu system (press the Menu button), or even review images you've already taken using the Playback button. Exit either of these modes when finished, and you'll be returned to Live View. However, if you select Dust Delete Data from the Shooting 2 menu, Sensor cleaning from the Set-up 2 menu, or either Clear settings or Firmware Ver. from the Set-up 3 menu, Live View will be aborted, and the T2i will return to normal operation.
