In this project we have studied the different methods of obtaining
photographic-quality digital images from conserved fragments
of carbonized papyri.
We have tested several film materials, scanned images from
film and paper copies, scanned directly from a sample, digitized
CCD camera images and even tried IR imaging and X-ray photography.
The various ways to produce digital images lead to different
results, and there's no simple way of measuring their goodness.
The measurements and tests show that the best contrast can be
achieved in the near-infrared band of spectrum. Still, better
spatial resolution in normal light may lead to better overall
impression. A variety of digital filters and other image processing
methods has been examined to enhance the images. A preliminary plan
of an image archive and papyrological information collection
based on hypermedia techniques is presented. This report, which
is available also via www, is an example of some possibilities
of such an approach.
