The depth of field in an image is the distance between the parts that appear in focus. When there's a big distance between the things that look crisp and sharp, it's known as a wide or deep depth ...

Shallow depth of field, sometimes called shallow focus ... Brimstone In order to create a shallow focus, you use a wide aperture (a low f-stop number) on your camera lens. This will create ...

The standard formula for controlling depth of field is to control the f-stop of the lens. And that is true enough. A wide-open aperture results in a shallow range of focus, and a small aperture ...

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 ...
