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 ...

The wider the aperture (the smaller the f-stop number), elements in front of and behind the object in focus appear soft or blurry. In both moving and still pictures, depth of field (DOF ...

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

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 variable aperture lens allows users to adjust the depth-of-field in photos more precisely. A report from The Information earlier this year suggested this feature will be on one of the iPhone ...
