Ondu pinhole

This is my Ondu pinhole camera.  It takes 120 format film.  By the use of baffles inside, it can take 6x6, 6x9 or 6x12cm images.  I prefer 6x9.  I sometimes set the baffles up so that the pinhole is offset which gives a "rise" effect when shooting portrait orientation images.  It comes with a magnetic filter holder, to which I have fitted a red filter for this photo.The shutter is a simple sliding mechanism, see here to the left of the pinhole.  My only criticism is that the red window for winding the film on is so dark it is very difficult to see the backing paper through it.  It is, however, great fun!
