Composition 9/11 - learning the basics

 Simplicity
In this photo you are mainly focused building burning instead of the buildings around it, and because there isn't anything in the background.

 Rule of thirds
You are mainly focused on what is in the upper left of the picture instead of what is around it.

 Lines
When you look at the photograph it makes you wonder when the lines end and where they begin.

 Balance
 There are subjects on both sides of the picture instead of one main focus.

 Framing
In this photo the bridge, water, and smoke all frame the buring tower.

Merger
In this photo the pole looks like it is coming from the mans head and everybody is partcially cut off.
