The Tragedy of 9/11

Balance

The two cranes are forming a triangle in the bottom left side of the picture.

It makes a nice different shape to the picture, which is mostly squares and rectangles. It also draws the viewer's attention to the wrecked building. Since the lines are diagonal as well, it gives some direction to the picture.

Lines

The lines on the skeleton of the building make it stand out among the wreckage. Since it also points to the sky, it gives the photo a solitary feel, that the person is standing there alone and desperate. There is no real direction to which the lines are pointing.

Off-Center
The main subject in this picture is the One World Center. But a secondary subject is the man closest to the camera. Both are off center. One can clearly see that the photographer kneeled on the ground to capture this moment in time.

Lines
This is clearly one of the best examples of lines that I've seen so far. Both sides of the memorial come together at a point. They compliment the fountain perfectly and give a feeling of comforting and peace. The picture is definitely one of my favorites because of the lighting, because it's amazing and beautiful.

Border

The wrecked building outlines the firefighter like a picture frame. The background is simple, and there are no other subjects to interfere with the camera. The border draws the viewer's attention like a magnet to the person in the middle.

Merger

In the back, there is a pillar of some sort that looks like it's a part of the escalator. That is definitely not a good idea. In order to get a good picture, the photographer, should get a good angle, so that people don't think that the pillar is part of the machinery itself.
