Canon EOS 90D For Dummies. Robert Correll

       Cover the viewfinder to prevent light from seeping into the camera and affecting exposure. The camera ships with a cover designed just for this purpose. In fact, it’s conveniently attached to the camera strap. To install it, first remove the rubber eyecup that surrounds the viewfinder by sliding it up and out of the groove that holds it in place. Then slide the cover down into the groove and over the viewfinder (Orient the cover so that the Canon label faces the viewfinder).

       Using Live View or Movie mode for an extended period can harm your pictures and the camera. Using the monitor full-time causes the camera’s innards to heat up more than usual, and that extra heat can create the right conditions for noise, a defect that looks like speckles of sand. More critically, the increased temperatures can damage the camera.

       A thermometer symbol appears on the monitor to warn you when the camera is getting too hot. Initially, the symbol is white. If you continue shooting and the temperature continues to increase, the symbol turns red and blinks, alerting you that the camera soon will shut off automatically.

       Aiming the lens at the sun or other bright lights also can damage the camera. Of course, you can cause problems doing this even during normal shooting, but the possibilities increase when you use Live View and Movie modes.

       Live View and Movie modes put additional strain on the camera battery. The extra juice is needed to power the monitor for extended periods of time. If you do a lot of Live View or movie shooting, you may want to invest in a second battery so that you have a spare on hand when the first one runs out of gas.

      1 Display the Quick Control or Live View screen.If the monitor is asleep or the screen is showing menus or your existing photos, press the shutter button halfway and release it to redisplay the Quick Control or Live View screen. The left image in Figure 1-22 shows the default photography screen as it appears in the Scene Intelligent Auto exposure mode. The right image shows what the camera looks like in an advanced exposure mode using Live View.FIGURE 1-22: To activate Quick Control mode, tap the Q symbol or press the Q button.

      2  Press the Q button or tap the Q icon to enter Quick Control mode.If you’re using the viewfinder to take pictures, the display changes to look similar to the one shown on the left in Figure 1-23. In Live View mode, the display appears as shown on the left in Figure 1-24.

      3 Select the setting you want to adjust.The currently selected setting is highlighted; in the figures, the Drive mode is active, for example. To choose a different setting, tap it or press left/right using a multi-controller to highlight it.On the Quick Control screen, the name of the currently selected option for the setting appears at the bottom of the screen, as shown on the left in Figure 1-23. In Live View mode (refer to Figure 1-24), the text banner initially shows the name of the setting you’re changing, with icons at the bottom of the screen representing the available options. The one surrounded by the orange box is the currently selected option.FIGURE 1-23: After highlighting the setting you want to adjust, rotate the Quick Control dial or Main dial to cycle through the available options (left) or press the Set button (not the center Joystick button) to display all options on a single screen (right).FIGURE 1-24: In Live View mode, tap or use the up/down Multi-controller keys to highlight the setting you want to adjust, and then tap, use the left/right keys, or rotate the Quick Control or Main dial to choose your desired option.

      4 Rotate the Quick Control dial or Main dial to cycle through the available options for the setting.As soon as you rotate the dial, the text label on the Quick Control screen updates to reflect the name of the setting. And on the Live View screen, the name of the setting you’re adjusting is replaced by the name of the selected option. In the right screen in Figure 1-24, for example, you can see how things look when you change the Drive mode from Single Frame to the Self-Timer: 2 second/remote option. (Chapter 2 explains these and other Drive mode options.) During viewfinder photography, you can also tap the setting icon or press the Set or center Joystick button to display all the available options on a single screen, as shown on the right in Figure 1-23. Tap, use the left/right multi-controller keys, or rotate the Quick Control dial or Main dial to highlight the option you want to use, and then tap the exit arrow to exit the settings screen. (In Live View mode, tapping the icon on the sides of the screen simply selects the option represented by that symbol.)

      5 Repeat Steps 3 and 4 as needed to adjust other settings.

      6 To exit Quick Control mode, press the Q button.In Live View mode, you also can tap the return arrow in the upper-right corner of the screen, as shown on the left in Figure 1-24. When using the viewfinder, you can tap the Q symbol that has the return arrow, as shown on the left in Figure 1-23.

       For some settings, the Live View preview updates to show the result of your choice. If you adjust the White Balance setting, which affects how colors are rendered, you see colors shift in the preview, for example.

       After you choose some options, additional touch-control icons appear on the options screen. For example, you may see an icon bearing an Info label. By tapping that icon or pressing the Info button, you can access settings that enable you to modify the characteristics of the currently selected option. Instructions throughout the book alert you to these hidden settings.
