ABSTRACT

Photography has long had an important place in archaeology, being used for on-site field recording and museum-based records. The Folkton Drums are the most remarkable decorated artefacts from Neolithic Britain, part of a wider group of decorated artefacts of chalk, antler and stone. Close-range photogrammetry, image-based modelling or structure-from-motion photogrammetry involves the construction of a three-dimensional model of something from two-dimensional images; it has been applied in the digital re-creation of archaeological artefacts and works of art. Technological advances make it possible to obtain dense and accurate three-dimensional surface data via photogrammetry and fine surface 2.5D detail via Reflectance Transformation Imaging (RTI). RTI and photogrammetry blur dichotomies; the images created are simultaneously the subject and the object – in many ways they are also neither. RTI involves the use of various things, including cameras, tripods, spherical balls or marbles, remote triggers and speedlight flash units.
