DEPTH OF FIELD
F16, 1/15 sec.
F2, 1/1000 sec.
Depth of field is the area of acceptable sharpness
in front of and behind the subject in focus. As
you get closer to your subject or as you open your
lens (e.g. from F16 to F2.8) the depth of field
becomes shallower. By stopping your lens down
(e.g. from F2.8 to F16) or getting farther away
from your subject this depth of field can be in-
creased.
The table below shows that when the camera-
to-subject distance is 3m, the depth of field at
F16 ranges from 1.93m to 6.93m.

looking
through
the viewfinder, you can ascertain the actual depth
of field.
