The focus is one of the fundamental elements of photography. Without it, we basically failed to direct the viewer’s gaze. There are photographers who are perfectionists and there are others, linked to photo journalism, that not so much. Robert Capa even wrote a book called ‘Slightly Out of Focus’ – and one of the most important photographs in history, a record of it on D-Day of World War II is in this way, slightly out of focus
This photograph below illustrates a way to direct the viewer’s gaze where to follow the photographer’s desire. The photographer has the whole picture to do this, and I did it in the most common segment, the center. Although the wide-angle lens customarily leaves every frame in focus, certainly the center, to which I have pointed out, has more than the surrounding elements.
