I took the above two shots of the exact same scene but reversed the focus points. The focus point on the first photo has the bottle in the foreground in focus. The second has the fence in the background in focus. I used a small F-stop. The first shot I focused on the foreground, held the shutter half way down to focus and then re-framed the shot, and finished pressing the shutter all the way down. For the second shot I repeated the above but changed the focus.
