The production of icons has been described by the monk Dionisios ek Fourna in 1728-1733. Icons are typically painted on a wooden panel with the egg tempera painting technique, over a layer of gypsum and glue (preparation layer). Continue reading →

Testing a Prototype 3D Structure Light Imaging System for Underwater Archaeology

While 3D imaging has become a revolution in land archaeology, it has experienced a difficult baptism underwater. Electrical equipment and water do not mix, plus many systems do not easily transfer underwater when you add currents, visibility issues, and salt into the equation. Approaches that have been attempted include acoustics, laser-based systems, and photogrammetry with each of these having varying success depending on site conditions. Continue reading →

Capturing and exploring textures in National Archive

Some time ago we made a visit to UK National Archive with James Miles to test RTI technology on a wide range of examples provided by the National Archive. James went back in September of 2012 for a second time to do more recording. Recently Dinah Eastop, a Curatorial Research Fellow from the National Archives has written two blog posts and presented the results of the work on their blog. Continue reading →

FCIR Imaging

The False Colour Infrared (FCIR) is based on the different response of materials in infrared radiation and combines visible RGB colour and infrared imaging. It has been used for materials differentiation and characterization, especially for painted works of art and pigments research. Continue reading →

RTI & Numismatics Conservation

RTI is considered to be a powerful documentation tool for cultural heritage applications. Previous work in the field of RTI in numismatic studies demonstrated advantages in identification and documentation issues in comparison to traditional approaches, as well as improved communication and dissemination abilities (Mudge et al. 2005; Gabov and Bevan 2011).
