When you look at a scene, you usually take it for granted that out of the whole vast view that you can perceive, you automatically choose one place to focus on. Your camera's autofocus mechanism has to do the same thing. It needs to focus at one particular distance in your scene. Ideally, you want that distance to be on your subject. Your camera includes a number of focus points spread around its field of view. By default, it automatically tries to identify which one of those points is sitting on the subject of your scene, but there will be times when you'll need to override that automatic mechanism, because it will have chosen the wrong point.
So you'll need to manually choose a focus point yourself, to force the camera to focus to a particular place. If you don't understand all this focus point stuff, check out Foundations of Photography: Exposure. To select a focus point, you press this button right here on the back of the camera. I know it's this button right here, because of this icon right here, which is supposed to look like a little viewfinder full of focus points. Now, don't get confused, because this icon that's supposed to look like a little viewfinder full of focus points looks a lot like this icon back here, which is actually supposed to look like a thumbnail view of a whole bunch of images, a grid of images.
So, this is a playback control. This is a shooting control. Notice, the playback control is in blue and that's true for a lot of controls on the camera: the Play button here, the Delete button over here, this little Printing button down here. So blue things are playback, white things are shooting. So this is the focus point selection tool and you'll remember that as you use it more. I press it and I get this display here in the upper LCD screen. Now, this same display is being shown inside my viewfinder right now. Obviously, we can't show you that from here, but you'll see the exact same thing in your viewfinder.
So, you can actually change focus points without having to take your eye from the viewfinder. Once that's selected, I have a number of different ways of changing the point. Probably the one you will use the most is to turn the main dial, and I say you will use this the most because the main dial is right behind the shutter button. So you can easily move your finger back to it. And you can see I am just cycling through all of the different focus points that the camera has. When I've gone all the way around the focus point horn here, I come back to this, which is all points selected. When it's showing this, that means the camera will choose a focus point for me.
That's the autofocus point selection. Now, I can also use the rear dial if you prefer using your thumb because you don't want to take your finger off the shutter button--that's fine. Or, of course, I can use the Quick Control Screen that we saw earlier. I prefer doing it back here rather than the Quick Control Screen, again, because I don't have to take my eye from the viewfinder. So that's focus point selection.
