Framing

In this photo the bridge, the sea, and the smoke center your vision on the city, also, the smoke does focus on the two big twin towers whit fire.

Avoiding Mergers

In this photo the red build make a bad view of the twin towers.
Our focus should be the twin towers, but the red build hinders.

Balance

I choose this photo because for me is a good example of balance, because the positions of the three mans made a geometrical triangle.

The Rule of Thirds

In this photo is easy to focus on the two mans. The mans are in the center-right of the photo, anything on the picture is a good focus, except for the two mans, because around the two mans is the same thing(disaster).

Lines

In this photo the lines are used to focus on the man. The lines are made by the Perception, as the lines of the streets, windows, and the big builds behind him.

Simplicity

In this photo the simplicity is the town, because as is the only thing in the picture is easy to focus on it.
