Composition 9/11

Lines

In this picture, the lines leading to the horizon are the fence and the building. Since the horizon is yellow, it also draws attention to the yellow in the Firemen's clothes. 

Simplicity

In this picture, the contrasting black clothes on the man against the lightness of the background tells the eye where to go, and since it is one of the only places the eye really goes, this picture is simple. 

Avoiding Mergers

In this  picture, the leading fireman's uniform lines merge with the background firemen's uniforms, so the lines merge together and don't separate the front fireman with the background firemen. This merge distracts from the furthest forward fireman.

Rule of Thirds

In this photo, the crane is off center, creating a better balanced picture. The crane works with the right top smoke and the major hole to create a picture with the rule of thirds.

Framing

This photo has a framing effect in how the photos of men on the paper frame around the mirrored part of the photo, drawing the viewers' attention to the man in the white shirt.

Balance

In this picture, the center (the fence part) creates an obvious triangle shape, which can be described as balance. It also contrasts with the smoke in the back and therefore creates a more prominent effect.
