Editing Ultraviolet (section)

==== Enhancing contrast of ink ====
Using multi-spectral imaging it is possible to read illegible [[papyrus]], such as the burned papyri of the [[Villa of the Papyri]] or of [[Oxyrhynchus]], or the [[Archimedes palimpsest]]. The technique involves taking pictures of the illegible document using different filters in the infrared or ultraviolet range, finely tuned to capture certain wavelengths of light. Thus, the optimum spectral portion can be found for distinguishing ink from paper on the papyrus surface.

Simple NUV sources can be used to highlight faded iron-based [[ink]] on [[vellum]].<ref>
