A slight variation of the above two methods which sometimes gets you that
extra frame is a follows. Before closing the back, wind the film so that
the leader has made one complete revolution around the take up spool, but
stop before both sprockets are engaged. Some film manufacturers have a long
enough leader that you can squeeze out an extra frame.
