It is always worth making a decision as to which part of a photograph should be in focus. Many photographers would automatically have focused on the outside of the bell as that is the part of the image that the most detail would have been visible. Focusing instead on the silhouette of the ‘clanger’ and leaving the aforementioned are blurred adds drama and a little mystery. To return to one of my pet obsessions; It allows the viewer to impose their own story. I am just dropping a hint.
