Once the postcards are distributed to students, they engage in
hands-on instructional labs in scanning. Students use SilverFast
AI software, in conjunction with the latest version of Photoshop,
using the currently available flatbed scanners (these are regularly
updated) to create uncompressed Tagged Image File Format
(TIFF) scans. The resulting archival files, in the 20Mb range, are
stored (and backed up) off line and can be examined by students if
extensive detail is needed. These files are the heart of any
database because they can be used for non-web purposes
