Nikon Camera F3AF - Manual (Page 57)

To illustrate depth of field, the following photos were taken with
the AF-Nikkor 80mm f/2.8 lens at a focused distance of 5m; the
only difference is that they were shot at various apertures. Con­
trol of depth of field enables you to create photos having selec­
tive focus (where the major subject stands out from the back­
ground and/or foreground) or overall sharpness (in which all
elements in the picture appear sharp). Depth of field imparts to
your picture a character all its own.
