It's narrow depth of field is something I'm just not really used to. Photography is an art that we need to learn by doing or even reading.
The most recent issue of Popular Photography, there is an article about getting the most out of your 50mm lens. Dang good read. It made me think about what a narrow depth of field means.
This shot is of the centerpiece of our table. Sure, I was bored, but I found it a good exercise in thinking about what an out of focus back ground can mean. I used this and the light on the table to provide me a most subtle background.
