Lesson 15: Depth of Field and the Circle of Confusion
In one of my previous articles on this website I have delved about the concept of depth of field (DoF) as well as the parameters that govern DoF. As you can recall, DoF depends on several aspects, chief among those being the aperture value in use. Bigger the aperture, shallower the depth of field and vice versa. There is, however, yet another concept that is closely connected with DoF and that is the circle of confusion.
