Can any of you tip me with e-mail addresses there I can learn how to fold a bellows? I need to construct a kind of special bellows for lens shade! I need something wide and low profile to use on the Schneider Super Angulon. I have an a Tomyama 6x24 cm wide angle camera I know this isnt a large format but those panorama guys probably cant help me out as this is not really their territory! Thanks.
