“Christian Epigraphy in Syracuse” workshop, May 15th 2015
CHSOS is invited speaker at “Christian Epigraphy in Syracuse” workshop, May 15th 2015. Since 2013 CHSOS has pursued diagnostics and documentation in Syracuse catacombs thanks to a research collaboration with Pontificia Commissione di Archeologia Sacra. Mural paintings and graffiti have been examined with innovative analytical and imaging technologies. CHSOS will present these studies. S. Stout,
How to document Historical Graffiti in Catacombs
This new paper discusses RTI (Reflectance Transformation Imaging) for documenting historical graffiti in Catacombs. Historical graffiti provide unique information on the uses of the catacombs over the centuries. Some of the graffiti of the catacombs of San Giovanni are contemporary with the epoch of the paintings that bear them (late antiquity), while others have been incised by
Free RTI training spheres set
For those who take the 5 days training course on multispectral imaging and technical 2D and 3D photographic methods it’s provided a free RTI training spheres set. It is composed of 4 spheres (diameter 14 mm, 6,5 mm, 3 mm,1 mm). These are designed for close up and macro RTI and are suitable for RTI applications
Reflectance Transformation Imaging (RTI) with Arduino
Arduino comes useful in many applications and even in art examination. I used it for Panoramic Infrared Reflectography. It just turned invaluable also for RTI (Reflectance Transformation Imaging). I had to do RTI documentation of graffiti in Syracuse catacombs and since the graffiti were over a mural painting it wasn’t easy to measure the distance between the
