If I rely on the DOF and focus a full-length portrait slightly in front of the subject, won't I get a plane of focus in front of the person that is sharper than the subject, and if there happens to be something in the shot at that distance like a piece of furniture, or some grass or plants, they'll be sharper than the subject won't they? DOF is only defined for a specific enlargement factor and a specific viewing distance (circle of confusion), right? So if I enlarge the resulting neg more than the guy who printed the DOF tables expected me to, the print will actually not necessarily be "in focus" where I want it to be? I guess we have to decide what size we want to enlarge the picture to before we shoot it... Simon.
