Our interns were tasked with bringing in an object they wanted to explore the texture of. They learned how to appropriately position an artefact for the most accurate results, adjust the necessary photography settings & light sequencing, & process their photographs to create a final RTI model

The image can be enhanced to exaggerate the surface relief and provide a better view of key details. The normals visualisation technique creates a false colour view of the normals of reflection, indicating the direction each surface faces, and giving a better idea of the overall shape of the object.

Creating an RTI involves photographing a subject while varying lighting angles in a controlled manner. Spheres are included in the photographs to record the angle & enable the processing software to calculate a matrix of surface normals that indicate the direction of reflected light from the surface

Often referred to as 2 1/2- dimensional imaging, RTI can offer a superior view of surface relief and texture compared to conventional photography. It can produce views of marks, inscriptions, and indentations to assist with readability, and create a visually engaging experience of the object

We'll be working with the digital team at the National Archives and Co-Leads Dr Euan Roger, Prof Jayne Carroll, Prof Adrian Bell, and National Trust & regional partners to build a digital resource that will enable researchers to find and make use of the incredible data in the Valor Ecclesiasticus.

They are developing valuable technical skills in high-resolution image capture, colour management, & digital file handling. In addition, they have gained hands-on experience in the safe handling of archival material, & learning techniques for ensuring preservation during the digitisation process.

The interns have been learning the digitisation process in our photography studio. This has involved operating our Phase One 150mp Cultural Heritage camera and Guardian Copystand. They have also been getting to grips with our Capture One photography software
