This is an example of shallow depth of field. Critical focus is important. Cousin David focused on the left eye highlight. Everything else is slightly out of focus. With point and shoots, and even with automatic DSLR settings, the computer avoids the wide open f-stop. The whole point is to focus the viewer on a particular area of interest. For portraits it’s the eyes. And the shallow depth of field gives you that ‘bokeh’ some photographers avidly seek. With auto-focus, I’ve really gotten lazy. But it doesn’t mean you should forget the rules. In order to ‘break the rule’ creatively, you need to know the rules. At least that’s my opinion.
