The basic concept behind the extended depth of field is that a specially designed phase plate is inserted at the back aperture of the microscope objecive. The phase plate creates a uniquely shaped PSF ...

Guide to depth of field designed for those new to self-shooting, covering focus, focussing distance, focal length, aperture and sensor. The depth of field in an image is the distance between the ...

Lens The lens and aperture are key factors in determining depth of field. Lenses are known by their focal lengths - 14mm, 50mm, 200mm. Their role is to bend the rays of light that enter through ...

Some Nikon cameras have a Focus Shift Shooting menu option. This feature enables you to set up the camera to take a series of ...

The small footprint of a CCD makes it hard for digital video cameras to emulate the short depth of field of film cameras. You’ll notice depth of field in movies when they have one actor close to ...

where everything is in focus Depth of field is controlled by the aperture. A larger aperture means a narrower depth of field.

The wider the aperture of a lens (which refers to the f-stop number, like f/2) then the greater the depth of field. The greater the depth of field, the easier it is to produce bokeh. As anyone who ...
