Part of a photographer's job is to pay attention to the components of an image. A small piece of trash can ruin a good shot, while the capture of a feature or moment that many people might miss can become the focus of a great image.
The image above shows part of an archway to a cathedral entrance. The one below shows Nature's patterns in the form of a monkey puzzle tree.
Just as in life, it seems that it is the little things that really matter.
