Depth of field describes how much of an image will be in focus--for example, if you're focusing on a subject's eyes, will the tip of the nose and the back of the ears also be sharp?

Suddenly the shallow depth of field seen in a Super-35 movie could be achieved on a micro-budget. It is worth noting for the purists, however, that a larger sensor technically makes for a deeper depth ...

Our approach to extending the depth of field utilizes the concept of point spread function (PSF) engineering to greatly increase the axial range clearly imaged in a single exposure. The basic concept ...
