The depth of field image is focusing on the subject but the background is like an invisible subject. For example, a flower is by the ground with its leaves. It focuses on the leaves but background is blurred only to that item is on focus.
The photo that I chose is related to shallow depth of field as the focus is by the Brooklyn Bridge but facing towards the ground. It also has a historic train track that use to be there but the subway system is underground when we are here.
