This report is the result of the project to restore the images from old photographic glass dry plates that had been stored at Yawata Works for 120 years, to turn the images into digital image data. This project was implemented from 2008 to 3 years. When handling old assets such as old photographic glass dry plates, the owner's intention is the most important. Based on a plan based on sufficient interviews with owners, we might develop experimental equipment and solve all owners' requests. This time, we had developed an experimental device that uses a brownie digital camera and a medical illuminated photography stand unit. In addition to realizing no damage to the old glass plates, we succeeded in restoring the image data of 43 million pixels and high resolution image data up to 150 million pixels. In this project, we were able to discover many evidence of World Heritage registration and discover various cultures and technologies of the Meiji era. We hope that this repot will serve as a reference for new research on old photographs.
