Basics of the relationship between focus and depth of field are explained in this section . • Depth of field When focusing , depth of field should be considered . Depth of field is the zone of sharpest focus in front of and behind the subject on which the lens is focused . It varies according to shooting distance, focal length and, above all, aperture. Smaller apertures (larger f-numbers) will produce a deeper depth of field where the background and foreground become sharper; larger apertures (smaller f-numbers) will produce a shallower depth of field where the background becomes blurred. Similarly, shorter shooting distance or longer focal length will produce a shallower depth of field, and longer shooting distance or shorter focal length will produce a deeper depth of field . Note that depth of field tends to be shallower in front of and deeper behind the subject in focus. Large aperture f/2 .B Small aperture f/ 32 102

Basics of the relationship between focus and depth of field are
explained
in
this section .
• Depth of field
When focusing, depth of field should be considered. Depth of field
is
the zone
of sharpest focus
in
front
of
and behind the subject on which the lens is
focused. It varies according
to
shooting distance, focal length and, above
all
,
aperture. Smaller apertures (larger f-numbers) will produce a deeper depth of
field where the background and foreground become sharper; larger apertures
(smaller f-numbers) will produce a shallower depth
of
field where the
background becomes blurred. Similarly, shorter shooting distance or longer
focal length will produce a shallower depth of field, and longer shooting
distance
or
shorter focal length will produce a deeper depth of field. Note that
depth of field tends
to
be shallower
in
front of and deeper behind the subject
in
focus.
