I make lens boards for my speed graphic from black mat board. Easy to
cut a bunch and have various focal lengths and zoneplates handy. I also
use black foamcore to mount pinholes in shutters. Easy and inexpensive.
Your local frame shop can be a source of small pieces of
matboard--especially if you are having them frame your work. Cheers,
Howard Wells
