Reflectance Transformation Imaging

Reflectance Transformation Imaging (RTI) is a computational photography-assisted technique that utilizes multiple lighting conditions to capture a series of images from a fixed camera position, aiming to virtually and interactively unveil the characteristics of the depicted surface.

The cenaculum
The Cenacle (from the Latin cenaculum, “dining room”), also known as the Upper Room (from the Koine Greek anagaion and hyperōion, both meaning “upper room”), is a room in Mount Zion in Jerusalem, just outside the Old City walls, traditionally held to be the site of the Last Supper, the final meal that, in the Gospel accounts, Jesus held with the apostles.
According to the Christian Bible, the Cenacle was a place in which the apostles continued to gather after the Last Supper, and it was also the site where the Holy Spirit alighted upon the eleven apostles on Pentecost.
The Israeli authorities administer the site, and is part of a building holding the so-called “David’s Tomb” on its ground floor.
