Ed, what are they doing? Pinhole photography? How is that related to zone plates in B+W? I am not sure I understand the verbage....

Thanks!

They use either pinholes or zone plates to form images on good old photographic film, either B&W or color. They aeem to be kindred spirits to us with their home-made camera gear and off the wall ideas.
