I'm building an 8x10 pinhole camera from a dilapidated Kodak Metalview camera. I've come across some intriguing images online made with "zone plates." They seem to work well with hign-contrast subjects and bright specular highlights. A quick search of APUG, however, uncovers no discussions about them.
Anybody here using zone plates for pinhole work? I've located posts on other sites via Google, but I was wondering whether anyone on APUG has first-hand experience using them.
