This photograph by Matt Stuart is a great example of a "usual seen in an unusual way" photo, and is very visually interesting. The most important decision tool the photographer used was to lower his camera to the ground, thus allowing the viewer to see only the feet of the subjects, as well as giving a good look at the lines and texture of the pavement. Another decision tool that came into play was "what else to include" (or in this case, what NOT to include). The photographer cut the heads of his subjects out of the picture. This incites some curiosity in the viewer, and highlights the more important parts of the image: the lines of the subjects legs and the color contrast.

The photographer here used his decisions to make a boring and generic lamp into interesting subject matter. First, he held the camera at a very weird diagonal angle. This allowed him to exploit negative space offered by the sky and place the building in an interesting location relative to the lamppost. Second, he used a worm's view. This gives the viewer a good view of the yellow focal point, and thus adds color contrast. It also includes a lot of the sky and prevents the shot from feeling busy or congested.
