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 ...

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 ...

F-stop is a consistent way to measure lens aperture, and helps photographers control exposure and depth of field. It is noted ... Taking photos at a higher f-stop requires a faster shutter speed ...

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.
