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 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 ...

Today, we want to go over one that gets used a lot: shallow depth of field. We'll review the definition ... you use a wide aperture (a low f-stop number) on your camera lens.

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 ...

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 ...
