Depth of Field is defined as the distance between the nearest & farthest object that appear in focus. Now I say appears in focus because there is really only one minute plane that's truly in focus. However, there is a distance before and after this plane that appears in focus. This is your depth of field. So there's two primary things to keep in mind that affect your depth of field, Iris and Focal Length. A shallow depth of field is where the background is soft but the subject is crisp. Unfortunately this a little tricky to get with video.

No problem, this lesson will show how your depth of field works and how you can manipulate it to your advantage. Using a shallow depth of field gives us a whole new level of creative control. This will be covered in the next lesson called selective focus.
