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.

Simplicity

This photo represents simplicity because there is only one thing for the eye to be drawn to. The falling man is the only thing that stands out against the lines of the building.

Lines

This photo represents the rule of lines because the smoke is billowing out in lines which draws attention to the people in the building. Also the lines are diagonal which makes the picture dynamic.

Balance

In this photo the two towers balance each other out. The smoke also helps create balance because the towers are a bit off center towards the right so the flames going to the left creates balance.
