9/11 Composition

Framing

In this photo, the buildings on either side of the explosion provide vertical boarders to the action and event taking place. The street light curving over the puffs of ash, smoke, and dust, as well as the stoplight at the bottom create horizontal frames for the subject. All of these objects frame the attack, and make it obvious what the center of focus is.

Avoiding Mergers 

From the girl placed in the middle of the photo, to the metal rail and buildings behind her, and also the smoke that looks like it's coming out of her back. The subject is interacting with the background without intention, and it appears as though she's on fire.

Balance

In this photo, the police officer and the distressed women are balancing each other out. If it were just one of them, then we most likely wouldn't know what's happening. Besides the people, there are objects on both sides as well.

Lines

This photo displays leading lines in a more subtle way. There's the line of the sidewalk running down the street, the lines at the bottom of the buildings, the lines on the signs, and the street light in the background. all of these lines draw our attention the subject of the photo, which is the person in the alley with the lines leading towards him.

Rule of Thirds

When looking at this photo, the first place you look is the firefighters on the crane. If you placed the rule of thirds grid on this photo, the subject would be placed in the bottom right line intersection. Our eyes draw to them first, before we look at the rubble. The rule of thirds draws more interest as well as attention to the subject. 

Simplicity 

This photo represents simplicity, because we can easily tell what it is we are looking at, and we know right away what the subject of the photo is. The blue background of the sky doesn't distract us from the main focus, and it also doesn't interfere with it.
