[QUOTE="Horoscope Fish, post: 147691, member: 13090"] Correct. Shooting from 5 feet at f/11 with a focal length of 55mm gives a DOF of just over twelve inches with an even split between front and rear focus or, roughly, 6" both in front of and behind the point of focus. Dropping down to f/16 at the same 5 feet and using the same 55mm focal length increases total DOF to just over 18" with a 60/40 rear/front split, again rounding the numbers slightly. Using 55mm at f/16 we can also move in a little closer, say three feet from the subject, and still have 3 or 4 inches of DOF on either side. Any closer than that and DOF begins to get really dicey. [I]Voila[/I]. [/QUOTE]
