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 ...

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 ...

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 ...

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 ...

The depth of field refers to the area in focus, in relation to the distance between the camera and the subject. This parameter is determined by four factors: aperture, sensor size, focal length ...

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

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 ...

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 ...
