I had never thought of the hat trick (new use for that term!) and that is quite brilliant.

I've never had the guts/imagination to try it (my subjects are far more ordinary), but I would be careful how much tension you put on the rewind lever. Too much, and it might "spring back" a bit when you pop the rewind button.
He was a pretty smart instructor. He knew some tips and tricks that I've never tried myself, and it was clear he loved film.
