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 ...

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 ...

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 ...
