Deep focus (or deep depth of field, as we would call it today) was dependent on innovations in technology. Faster filmstock ...

This can create meaning in an image. Depth of field means how much of the image is in focus. A photograph might have: narrow depth of field, where only a small part of the image is in focus larger ...

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 ...

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 ...

ISO is the sensitivity of a digital camera sensor or film to light. A low ISO (e.g. 100-200) gives you a clean image in ...

In the 20th century, photographers had to use maximum open apertures to compensate for slow film speeds, allowing for ...
