Overview
In some cases, it may be desirable to have the entire image sharp, and a large depth of field (DOF) is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background. In cinematography, a large DOF is often called deep focus, and a small DOF is often called shallow focus.
