MAKING USE OF THE DEPTH OF FIELD
When you have a subject in focus, there is a range
in the fore and the background which is clearly
defined in the picture. This range is called depth
of field. The larger the F number becomes, the
wider this clearly defined range becomes, and
the background becomes sharper. On the con-
trary, the smaller the F number becomes, this
range becomes less wide, while the background
loses contrast and out of focus. By using these
properties of the depth of field with creativity
and imagination, you will be able to take pic-
tures which will have your own personal im-
print.
