Shallow depth of field? Im still trying to understand my aperture triangle and I'm looking at images to get an idea of shallow depth of field and a wide depth of field.

Here are some images showing narrow & wide depth of field.

In the top images the chest pieces are much closer and the outside is blurred and the narrow depth is concentrating on the chest pieces.

The bottom image is wider getting the staircase in an the stairs this is a much wider image and everything is in focus.
