My husband, Paul Pennington, wrote an article on building your own pinhole camera which is featured in the "Winter 2007:Retro" publication of Arts Perspective Magazine. I did the illustrations for his article. You can find the publication at news stands throughout the Four Corners area. Once they put this issue on-line, I'll add a link. In the meantime, here is a link to Arts Perspective homepage.
Update: The article on building a pinhole camera is now on-line. Some of my illustrations didn't make it to the on-line version, so to see all the drawings, pick up a copy at news stands or check into a subscription. Also, I highly recommend reading the article on our friend and amazing artist, Ron Fundingsland. Ron is a master printmaker, working often in mezzotint and aquatint.
