Customizing the Canon EOS Rebel T7i/800D Live View Display
By default, the Live View display on the Canon EOS Rebel T7i/800D offers the data shown on the left in the figure when you’re taking photographs; in Movie mode, the default display appears as shown on the right. Black bars appear at the top and bottom of the movie display to indicate the boundaries of the 16:9 movie frame.
As is the case with other information displays, the type and amount of data that appears depends on your exposure mode and whether the camera is set to take still photos or shoot movies.
You also can vary the amount of data that appears in either display by pressing the Info button. The following figure shows the four other displays available for photography. In Movie mode, the Histogram display isn’t available.
Additionally, you can add one of three grids to your screen, which can be helpful when checking alignment of objects in the frame. To enable or hide the grid, open the Shooting Menu and look for the Grid Display option, featured in the next figure. As with other menu options, where you find this one depends on your exposure mode. For regular photography in P, Tv, Av, and M modes, the option lives on Shooting Menu 5, as shown in the figure. In other still photography modes, it’s found on Shooting Menu 2. In Movie mode, you find the option on Shooting Menu 4 in P, Tv, Av, and M modes and Shooting Menu 2 in other exposure modes.
