The best way to figure out what would happen if you used a fibre optic pinhole would be to just make one and see what happens.
For those of us who are curious how fibre optics work, here's what I understand: (Sorry if this all sounds technical, but even pinhole photography must obey the laws of physics) Light that enters a fibre optic at an angle will exit the fibre optic at the same angle because it bounces around the inside of the fibre (see http://www.stamweb.com/Article%20Fiber.htm ). If light enters the cable from all sorts of angles, the light coming out of the cable will be scattered all over the place. A beam of light that enters and travels PARALLEL to the fibre never bounces off the walls, therefor it exits the fibre exactly as it entered. The fibre optic scopes that surgeons and big-shot movie directors use have LENSES on the end that FOCUS light rays so the rays travel parallel into (and out of) the fibre optic cables. Without a lense, a fibre optic pinhole would just scatter light around the inside of the camera (except directly behind the fibre optic cable where the image will only be the size of the cable's thickness). With a lense, a fibre optic pinhole would no longer be a pinhole. But it's a good idea though... __________________________________________________ Do You Yahoo!?
