Slow Portraiture

I recently had my picture taken by ldste with a pin hole camera.  I love them as pictures as, although they aren't all neat and in focus etc they have a really beautiful feel to them.  As the aperture was open for a fair while for each of these shots I had to be still (not my fortè!) and the camera had to be still, i think this has a lot to do with the lack of focus, also you are guessing, counting, the time to leave the lens open for so a lot of it is pot luck.  Beautiful results though.
