This is the only one worth reporting on. Its taken in traffic at night, but I flipped the image because it works better like that. Unfortunately, this doesn't really showcase the zoneplate qualities, unless its to give the lights a softer glow. But it certainly has a lot more life than the other shots on the roll. http://groups.yahoo.com/group/pinholegallery/files/DSZP/zpdashboard.jpg Focal length, 90mm, ASA 100, exposure 4 blocks at 25mph. I'm about to build a rig to use as a mount for the cameras that will fit in my moonroof opening and allow me to also reach up and trigger the shutter open and closed.
