Digital cameras present photographers with an ever-increasing array of automatic and semi-automatic shooting modes. Most of these center around different ways to expose your shots – however, many cameras also give options for different focusing modes (auto, continuous focusing for moving subjects and manual). It’s no wonder then that many photographers never make use of their camera and lens’ ability to focus manually.
In macro and close-up photography situations, depth of field tends to become very shallow, so having control of your point of focus is very important. Manual focusing puts the control completely in your hands when shooting in this very precise setting. In order to get macro subjects really in focus, a complete depth of field is very important. The way to do that is to use a small aperture (at least f/25) and a dedicated macro lens to get close enough to your subject.
