My paper was Ilford multigrade RC, but I'd be surprised if fiber would give you any better results.
Haha - thanks for the reply. The aperture on the camera I would be using is f/240. If my calculations are right, then at ISO 20 my exposure time would have to be around 10 hours (if the correct exposure time was 30 seconds at f/16 at ISO 100). So lowering the ISO below 20 would make it even more ridiculous. Maybe I'll stick to day time shooting
