I found that the most shallow depth of field is achieved by zooming in (having a longer focal length) and getting as close to the subject as possible.

This diminished field of focus makes for some very cool effects! I didn't add any extra blurring or the like, yet some areas that are fuzzy look like they are right next to areas that are in focus. I found that a shallow field of view really appears to bring the elements of a photograph closer together (hence the name). I also discovered that by using an object with more than one plane (e.g. a circular object that fades backwards out of focus as opposed to the flat edge of a pin or coin) and surrounding it by a host of many other materials in a certain way (in this case in a lower orientation than the main subject), the horizontal plane of focus isn't, at first glance, %100 defined. The eye instantly goes to the text, which is the main focus, helped along by utilizing the rule of thirds (and then bending it a little bit) and not centering the main focus in the middle of the image. Many elements such as these can make photographs a lot more compelling.
