Digital Humanities Lab seminar series. Carla Schroer & Mark Mudge (CHI Cultural Heritage Imaging):"Building Scientific, Reliable and Reusable Complex Digital Representations: The Digital Lab Notebook". Join us for drinks and nibbles following the paper!

Carla Schroer is co-founder and director of Cultural Heritage Imaging (CHI) a non-profit corporation that develops and implements imaging technologies for cultural, historic and artistic heritage and scientific research. Carla leads the training programs at CHI along with working on field capture projects with Reflectance Transformation Imaging and photogrammetry. She also leads CHI’s software development activities. She spent 20 years in the commercial software industry, managing and directing a wide range of software development projects.


Mark Mudge is President and co-founder of Cultural Heritage Imaging. He has been involved in photography and 3D imaging for more than 30 years. He is a co-inventor, with Tom Malzbender, of the computational photography technique, Highlight Reflectance Transformation Imaging. He has published 14 articles and book chapters related to scientific imaging of cultural heritage material and its long-term preservation. He serves on several international committees, including The International Council of Museums' (ICOM) Documentation Committee (CIDOC).


How do we capture, process, and archive digital cultural heritage data in a way that is scientific, transparent, and reusable by others, both today and in the future?

This seminar features the Digital Lab Notebook (DLN), a new set of software tools for the near-automatic recording and archiving of computational photography-based digital representations and their contextual and process metadata. These computational photography techniques include Reflection Transformation Imaging (RTI), 3D Photogrammetry, Multispectral Imaging (MSI) and sets of documentary photographs.

The DLN serves the same function as a written scientist’s lab notebook. It permits a digital representation to be qualitatively evaluated for reliability and fitness for purpose by others. This provides the opportunity for informed reuse of cultural heritage digital documentation.

The seminar will explore the necessity for transparent evaluation of scientific digital representations. The goal is to establish the conditions under which a “real-world“ artifact can be digitally represented as a “digital surrogate”, which can reliably serve as a digital stand-in usable for subsequent scientific or scholarly examinations. The DLN dramatically simplifies the process of scientific imaging. It also manages the creation of archival Submission Information Packages (SIPs), built in conformance with international standards (the CIDOC/CRM).  The DLN’s Archiver tool prepares image data, built digital representations and their scientific metadata for intake into long-term preservation environments.
