I found the following tip to be helpful if you want to set up an interview to look professional. Here's what was on the site we were reading about How to Set a Scene, "Set your F Stop or aperture like the pros. To make your interview look like a “60-Minutes” television show, set your video camera to your lowest (1.6) manual F stop to compress the depth of focus. Set up your camera about 15 feet from subject and zoom into the proper framing, which will further compress depth of focus. To focus, zoom in tight and manual focus on the eyes, then zoom back to the proper framing. The background should appear slightly blurry yet the subject’s eyes will appear crisp."
