Macro

I want to learn how to take pictures where the image is sharp and crisp and everything behind it is blurry. Yesterday I tried while waiting in the car, using my macro setting on my camera.
Not bad...see how blurry the speedometer looks? Are those numbers?

A Little Lesson:

Keys will never look as beautiful as Kiera Knightly no matter how good I get at this.
Man my car is dusty.
