Cropping

This photo is an example of cropping because there are obviously more men involved in the gathering. However the photographer focused on Bush and the firefighter. This makes the picture dynamic.

Viewpoint

This photo represents viewpoint because the photographer is getting a worm's eye view of the tower collapsing. The photographer is underneath the tower instead of level with it.

Depth

This photo represents depth because there are two main parts of the picture. The one in front is in focus and the one in back is out of focus but is still a focal point, which makes the picture dynamic.

Symmetry

This photo represents symmetry because the two towers create symmetry. It is also dynamic because the smoke going to the left breaks the symmetry.

Avoiding Merging

This picture represents Avoiding merging because the two parts of the photo are not competing. They are positioned just right to fit the subjects without clashing.

Framing

This picture represents framing because the main subjects are framed by the pictures of the victims. The main subjects are the people looking in the mirror and the framing draws the eye to them.

Rule of Thirds

This photo represents the Rule of Thirds because the main focus of the picture is not completely centered. The firefighters, which are the subject, are shifted to the right. This makes the picture dynamic because you can see the fire and rubble in the background.
