Your Rebel T6i/750D camera's touch screen works much like the ones found on smartphones and other touch‐based devices, such as an Apple iPad. When the touch screen is enabled, as it is by default, you can simply touch the monitor to choose menu commands, change picture settings, scroll through your pictures, and more.
Familiarize yourself with these touch screen moves, called gestures by those who feel the need to assign names to things such as this:
Tap: Tap your finger on a screen item to select it. Give it a try: First, press the Menu button to display the menu screen on the monitor, as shown on the left in the following figure. Along the top of the screen, you see one highlighted icon, representing the current menu, and a row of dimmed icons representing other menus. On the left side, Shooting Menu 1 is the current menu. To switch to another menu, tap its icon. For example, tap the icon for Setup Menu 2, labeled on the left in the figure, and that menu appears, as shown on the right.
Tap the Setup Menu 2 icon to display that menu.Drag: Drag your finger up, down, right, or left across the screen, according to our instruction. To try this gesture, first display Setup Menu 2 and tap the LCD Brightness item, shown on the left. Now you see the screen shown on the right, with a thumbnail view of the last image you shot. Now drag your finger across the scale at the bottom of the screen to adjust the screen brightness. Reset the marker to the middle of the bar after you're done playing around — the default brightness setting is best for giving you an accurate indication of picture brightness.
Tap the LCD Brightness item (left) and then drag left or right across a scale to adjust the setting (right).On this particular screen, you see suns at either end of the scale. You can also tap them to raise or lower the value represented on the scale. Either way, tap the Set icon to implement the setting and return to themenu.
Swipe: Drag a finger quickly across the screen. You use this gesture, known in some circles as a flick, to scroll through your pictures in playback mode.
Pinch in/pinch out: To pinch in, place your thumb at one edge of the screen and your pointer finger at the 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 onpictures during playback.
You can control two aspects of touch screen behavior:
Adjust (or disable) the touch screen response: You can choose from three settings, accessed via the Touch Control option, found on Setup Menu 3 and shown here.
Control the touch screen response through this menu item.Standard: This setting is the default. The touch screen is enabled and is set to respond to a "normal" amount of pressure.
Sensitive: This setting makes the touch screen more, er, touchy. That is, it responds to lighter touch. Oddly, though, Canon says that the camera may be slower to respond to a very quick tap at this setting. Your mileage may vary.
Disable: Select this setting to disable the touch screen function.
To restore the touch function, use the alternative menu selection techniques that we explain in the next section to access the Touch Control option and change the setting back to Standard or Sensitive.
According to the manual, the Sensitive setting simply provides a "more reactive touch response than Standard." Don't confuse this with pressure sensitivity, which is how hard you press on the screen. Canon explicitly states that the monitor is not pressure sensitive and can be broken by sharp objects such as fingernails and pens.
Drive people crazy with touch screen sounds: Here's an option that you can use when you're in the mood to annoy people within earshot of your camera: Tell the camera to emit a little "boop" sound every time you tap a touch‐controlled setting. To do so, visit Shooting Menu 1, and look for the Beep setting, shown here. The option that keeps the boop silent is Touch to Silence — silence indicated by a little speaker with a slash through it — as shown in the figure. Change the option to Enable to turn on the sound effect. The Disable setting turns off both the touch screen sound and the normal beep tone that occurs when the camera finds its focus point.
Set the Beep option to Touch to Silence to prevent the camera from making a sound when you tap a touch‐controlled item.
One final point about the touch screen: If you connect the camera to a TV or monitor, the touch screen will still work as long as it's enabled. Just make sure to touch the camera, not the TV. Don't fret; if you would rather use the old‐fashioned button‐push method of selecting menu options and playing back photos or movies, you can.
