Depth-of“Fielci
Depth-of-field is the area that is in focus in front of and behind the subject
which is also in focus. When the aperture is smaller (i.e. when the
aperture value is larger), the area in focus is longer, and this is called a
deep depth-of-field.
Conversely, when the aperture is larger (i.e. when the aperture value is
smaller), the depth-of-field becomes shallower.
Depth-of-field has the following properties.
(1) The larger the aperture value, the deeper the depth-of-field.
... increase the aperture value to increase the depth-of-field.
(2) With the same aperture value, a greater depth-of-field will be obtained
with a lens with a shorter focal length.
... a wide-angle lens or the wide angle setting on your zoom lens
gives greater depth-of-field.
(3) With the same aperture value, a greater depth-of-field can be
achieved by moving further away from the main subject.
(4) When the subject is in focus, the depth-of-field will be shallower in the
front and deeper behind the subject.
