The question of how much storage space would be required for the thousands of images we would receive impacted a number of basic technical decisions. Bitonal scanning would not represent the
photographs adequately so grayscale or color images would be required. We felt confident that JPG2000 as a reliable file format for these kinds of materials. Though the Yale Daily News is an essential part of research at Yale, we were not undertaking a scanning project to replace the print and microfilm versions of the YDN, but merely to provide access. JPG2000 allows large amounts of information to be stored in a compressed form, without the compression artifacts and
other data losses inherent to JPEGs.
