Lambrecht) described in “Way Beyond Monochrome Second Edition,” co-authored by Ralph W. Lambrecht and Chris Woodhouse. Considering the sizes of electronic components currently available in Japan, I modeled it for 3D printing. Permission to publish this online was obtained from Ralph W. Lambrecht. The “Laser Alignment Tool” is placed directly beneath the lens mount and rotated around the laser beam's center. A tool (T3) to facilitate rotation was also modeled. This is optional. Detailed instructions for using the “Laser Alignment Tool” are provided in “Way Beyond Monochrome Second Edition”. Therefore, no explanation is given here. “Way Beyond Monochrome Second Edition” is a technical book on silver halide photography exceeding 500 pages. This book contains a wealth of detailed know-how that any silver halide photography en
