Do you know the Photoshop plugin called FocalPoint 2 from OnOne?
If not I recommend that you check it out – they have a free trail you can try be for you buy – if you like to fool around with  depth of field in your photos.

I use FocalPoint 2 on the photo above, to get the bokeh effect around the FedEx truck. And that is just one of the many things you can use the plugin for.
