Camera Back
The back of the camera is where things begin to get interesting. It contains lots of buttons and other goodies. You can consider this the central hub of the camera, with the top coming in a strong second.
Take a look at the nice photo I took of the Canon T6i. Not bad, if I don't say so myself.
1.
Menu Button: Press this button to access many of the options and settings available to your camera.
2.
Info Button: Press this button to display either the electronic level (if equipped) if in viewfinder mode or the rear LCD options if in live view mode.
3.
Optical Viewfinder Eyepiece: Look through this tiny window while in viewfinder mode. The viewfinder sees what's in reality, not what the camera's sensor sees. This is a wonderful option for tracking subjects because it keeps the scene as bright as possible, not matter the camera's settings. The light and scene that travels through the lens and that bounces off the internal mirror is what you'll see when looking through the viewfinder.
4.
LCD Monitor: When activated, you may view your scene on this screen. It's also responsible for displaying many settings and playback of both photos and video. When in video mode, this is the screen you'll be looking at.
5.
Eyecup: This piece is oftentimes constructed of soft rubber and it intended to shield the photographer's eye from external light.
6.
Dioptric Adjustment Knob: Some people call this the diopter. This is the device that adjusts the clarify of the scene when someone looks through the viewfinder. If you wear glasses and can't seem to focus your camera in this mode, you may want to try adjusting the diopter.
7.
Playback Button: Press this button to review any photos or video you've taken.
8.
Delete Button (Trash Can): While reviewing your images or videos, you may press this button to delete any you don't want.
9.
Live View/Movie Shooting Mode: When you turn on your camera, it'll most likely be in viewfinder mode. To change to live view shooting mode, press this button. If you press it again, your camera will switch back to viewfinder mode. If you're in movie mode, pressing this button will begin recording. Press it again to stop recording.
10.
Av +/- Button: This button controls the exposure compensation feature. On the T6i, press and hold this button while turning the top dial to make your scene either brighter or darker.
11.
Q Button: The real name of this button is
Quick Control. When pressed, it allows you to quickly access many of the camera's functions and settings right on the rear LCD screen. This works in both viewfinder mode and live view mode.
12.
Multi-Controller/Set Buttons: These buttons control many of the camera's functions as well as aid in navigating the camera's menus.
13.
Focus Point Selection Button: Press this to switch between auto-focus modes. This button also serves as a custom back button auto-focus control. And finally, it also returns the camera to normal view after zooming into a scene and while reviewing photos (next).
14.
Zoom Button: When focusing on a scene in live view mode, you may press this button to enlarge, or zoom, into the scene. Also, when reviewing photographs after they've been taken, you may press this button to enlarge them to view them more closely.
