(Figure ) is a little more out of focus, and so on. By the time you get to the last
image (Figure ), the subject is barely recognizable as a person. It is probably a little
too out of focus for most purposes.
When you first start playing with this, you may find that the depth of field on many
of your lenses, especially the zoom lenses, is too great to be able to get thi
