I am not the first to have done this and I'm sure I won't be the last but it was fun and I intend to try a few more shots with it. I had a lens from an old desk magnifier and a brass barrel which just happened to fit it perfectly. So a spot of glue and a Speed graphic lens board later I was in business. The focal length worked out at around 8 inches which meant a working aperture of f4. Because this wasn't going to be the best corrected of lenses I felt that a lens hood would be a mandatory accessory. I am very proud of my low tech solution. The image was made on Wephota Ortho film f4 at 15th sec and developed in Fotospeed FD10 for 6 minutes.
