2. Press the Set button, and then choose the metering mode that you would like to use
(I recommend starting with Evaluative) (B).
3. You can also change this setting on the LCD panel on the top of the camera. Just
press the Metering Mode selection button and use the Main Dial to scroll through
the different settings (C).

Shooting with the AE Lock feature
Once you select your metering, you can lock that setting in your camera temporarily if
you want to recompose your image—for example, if you are in an environment where
there is sufficient light on your subject but the background is significantly brighter or
darker. The metering in your camera is continuous, meaning it will change depending on
where the center of the viewfinder is pointed. If you want to compose the image so that
the person is off-center, the camera will meter the wrong part of the scene.
To correct this, you can meter for one part of the image (your subject), lock down those
settings so they don’t change, and then recompose the scene and take your photo. Here’s
how to use the AE Lock feature on the 70D:
1. While looking through the viewfinder, place the center
focus point on your subject.
2. Press the AE Lock button to get a meter reading and
lock the exposure settings (Figure 4.7). You’ll notice an
asterisk just to the right of the Battery check icon inside
of the viewfinder, which indicates that you have locked
your exposure.
3. Now recompose your shot and then take the photo; your
camera will maintain the exposure of the area where you
originally locked it.
