Took these images of the La Brea Tar Pits in Los Angeles.
For the image above I used a Lensbaby 3G, which I believe, is no longer in production. It allowed me to to alter the focal plane and lock it in place for both exposures. Though it is not apparent here, this allowed the blur to have dimension as well. You may see that on other shots I have where the subject is closer to the camera.
