Seals in Monasterium.net
Two components
Image Metadata
Depiction as complete as possibleFront Back
Drawbacks‡ Digitisation has to be cost effective‡ Images need to be “good enough to use”‡ Not intended as “preservation digitisation”‡ No special care is taken to make the images of seals as good
as possible – the charter as a whole is the main focus
Main equipment: fixed lighting
Camera view
