Illumination of Material Culture Symposium (II)
Friday 26th October 2018; Digital Heritage Congress 2018

Introduction (Graeme Earl, Ashira Loike, Carla Schroer and Anna Serotta)
This symposium provides a follow up to the two-day symposium with the same name organized at the Metropolitan Museum of Art in New York City in March 2017, that was supported by the National Endowment for the Humanities (NEH), Metropolitan Museum of Art in New York City and Cultural Heritage Imaging (CHI).  see (https://www.metmuseum.org/about-the-met/conservation-and-scientific-research/projects/rti- symposium)

A wish list for computational photography (Graeme Earl)
Since the first symposium I have been reflecting on the fascinating developments in the area of computational photography described there. In this very short talk I will identify three areas where I hope for translation and innovation in graphics and human computer interaction research.

Integrating Multispectral Imaging, Reflectance Transformation Imaging (RTI), and Photogrammetry for Archaeological Objects (Chantal Stein)
At the last symposium we showed how we combined RTI and photogrammetry to study tool marks on a marble fragment from Sardis. In this second case study we additionally combine MSI to study paint application on an Egyptian wood sarcophagus fragment, with some discussion about bias and object narratives.

Practical Applications for Integrating Spectral and 3D Revisited (E. Keats Webb)
This presentation will build on the work described in 2017 and provide an introduction to the author’s recent work on improved image-based 3D reconstruction. It focuses on wavelength and sharpness, and the use of a modified digital consumer camera as a scientific tool for conservation documentation.

When multiple lighting angles reflect on translucent stone surfaces: some issues for the MLR imaging technique (Hendrik Hameeuw & Vincent Vanweddingen)
Even for translucent and close to transparent stone objects Multi-Light Reflectance imaging methods produce good interactive datasets. Nonetheless, when the results are assessed in detail, issues on the correct estimations of the relief pop up. This presentation will discuss these issues.

Journeys between 3D and 2D (Mark Mudge)
This talk discusses 2D outputs from 3D data, and show Digital Elevation models from paintings, including the Diego Rivera mural gold leaf icons from Albania.

A New Web RTI Viewer for Collaborative Scholarship and Public Engagement (Taylor Bennett)
The University of Oxford's Departments of Archaeological Science, Computer Science, and the Centre for the Study of Ancient Documents in the Faculty of Classics are collaborating with MOLA (Museum of London Archaeology) to develop an open-source web-based viewer for Reflectance Transformation Imaging (RTI) files. The Oxford web RTI viewer provides layers for drawing and annotation for collaborative scholarship, and allows recording the viewer settings, such as light angle and rendering parameters. The web RTI viewer is being developed as part of an effort to crowd-source the epigraphy of Roman stylus writing tablets from the 1st century AD that were discovered in London between 2010-2014.

3-3:30pm Coffee Break

Sharing Conservation research with the public at Cooper Hewitt Smithsonian Design Museum (Sarah Barack, Jessica Walthew, Chris Gauthier, Adam Quinn and Nolan Hill)
Cooper Hewitt Smithsonian Design Museum recently completed the conservation and technical study of an elaborate ormolu Surtout de Table (table centerpiece) made ca. 1805, designed by Pierre Philippe Thomire. The work is the centerpiece of the exhibition “Tablescapes” at Cooper Hewitt (October 2018- April 2019). Conservation treatment included an overall cleaning that revealed contrasts of matte and shiny surface textures which we documented with RTI. We also 3d laser scanned two of the components to compare their shapes more precisely, suspecting that one is a surmoulage (a replacement part cast off of an existing part, rather than using the original molds). We worked with Taylor Abscher at NYU's Laguardia studio and were able to scan the shiny reflective surfaces effectively without any temporary applied surface coating using the Faro Edge (a blue light laser scanner). In the gallery, a touchscreen digital kiosk allows visitors to learn more about the conservation work with a short video on the overall conservation treatment, produced by our in-house videographer. In addition, our digital developers created an interactive display with both the RTI files and the 3d scans. This project required collaboration for the successful dissemination of technical research. Collaborating with our digital and video teams, we are able to share conservation imaging research in the exhibition and we are working on the launch of a Conservation channel to showcase this work also in online formats.

The Digital Lab Notebook (Carla Schroer)
A lot has happened in the development of the DLN tools since the first symposium. This talk introduces the recently released beta tools and plans for additional development.

Recalibrating the museum: the digital/ physical repatriation of Te Hau-Ki-Turanga. (Brinker Ferguson)
3D imaging work at the Museum of New Zealand and indigenous data sovereignty.

Galvanizing Digital Preservation Using Crowdsourced, Community-Based Efforts in Endangered Regions (Scott Purdy)
Through recent efforts in Venezuela, Syria, and with Native American tribes throughout North America, the Arc/k Project demonstrates what can be achieved via remote teaching of local citizen scientists inside their own communities.

Followed by planning of Illumination of Material Culture Symposium (III).
