Abstract

Testing at the Library of Congress and other institutions has determined that there can be greater than 3000ppi of real information in original film negatives and transparencies. This exceeds the real capture resolution of virtually all digitization systems which capture the entire film in a single image. The limitations of optics, sensors, and light restrict the effective resolution achievable in a single capture to substantially less than the information available in the original materials. The aim of this project was to develop a system to combine multiple image segments acquired at very high resolutions to create a single merged image that effectively contains the total information available in the original film. There are several commercially available solutions which can be used to perform this task, however, none of those tested produced optimal results. The project was specifically focused at multi-segment monochrome capture of large format photographic negatives from the LOC Prints and Photographs (P&P) Division, however the process developed is applicable to a wide range of applications.
