There are lots of things you can do with your smartphone to improve the photos you take.

To specify a particular focal area in a photo:

1) Open the photo app and compose a scene.

2) Press and hold on the screen on the area that you want to be the main
focal area – a colored square appears over the focal area.

3) Keep holding on the screen until the AE/AF Lock button appears at the top of the screen (AE is for the exposure of the photo. AF is for the Auto Focus). This indicates that the focal point has been set where you specified it, and will remain there once you remove your finger from the screen and move the camera.

To select an exposure manually:

1) Open the photo app and compose a scene.

2) Press and hold on the screen on the area that you want to be the main exposure area, in the same way as for locking the focal point.

3) The AE/AF Lock button appears, to indicate that the exposure has been locked at the point within the colored square – this will provide the exposure for the final photo.

4) If required, drag the slider at the side of the colored square to alter the exposure for the selected area.
