I have a CI5000 Polaroid Film Recorder, and if anyone is interested in developing a Photoshop or similar file to print zone plates with varying focal lengths, I would be interested in working on this project. I don't really have the knowledge to develop the file, but I would be able to print them out and share with other pinhole discussion members who would be willing to work on this project. Michele
