It proved invluable in showing me that I had a light leak where the holder sat and needed to add felt strips where the film holder made contact. It also showed me that I had a vignetting effect I didn't want. Because of the instant pictures I was able to diagnose the problems and fix them very quickly. The polaroid is also a great way to check the alignment of shots before using conventional film, although it is somewhat expensive. I recommend the Polapan 72, a high speed B/W film that does not require coating as other types do. My picture on Pinhole Day was with the Bender. I'm very happy with it. > > > --__--__-- > > Message: 12 > Date: Thu, 03 Jan 2002 11:38:26 -0600 (CST) > From: "Gordon J.
