PHOTOGRAPHIC TECHNIQUES

Aperture and Depth of Field

Depth of field is the area of accept-

able sharpness in front of and be-

hind the subject in focus. The larg-

er the F-number used (from F2.8
to F22), the deeper the depth of
field. On the contrary, the smaller
the F-number (from F22 to F2.8),
the shallower this zone of accept-
able sharpness.

The table on the opposite page

shows that when the camera-to-

subject distance is 1m, the depth

of field at F4 ranges from 0.91m

to 1.12m.
