> Depth of Field

You saw this image earlier. It is
a good illustration of how telephoto
lens settings minimize depth of field.

Now
that we have established that the ability to manipulate
depth of field is important, here's the nuts and bolts
of how to do it.
There
are three ways to alter depth of field.
1)
Focal length:
As we discussed, telephoto lens settings limit the number
of things in focus. That is, they decrease depth of
field. Wide angle lenses increase depth of field.
The
illustration at the right, shot with a telephoto lens,
has a very narrow depth of field. The kid is in focus--the
close sand and far water are not.
