Additional possibilities

Additional Spectral RTI training workshops may be scheduled for imaging teams involved in spectral imaging and interested in adding raking or RTI texture imaging. While funds from the National Endowment for the Humanities last, we can come to you. Contact project director Todd Hanneken, thanneken@stmarytx.edu.

Workshops on Integrated Spectral Reflectance Transformation Imaging (Spectral RTI)

Led by Dr Todd Hanneken (Jubilees Palimpsest Project, St. Mary’s University) and Ken Boydston (president of MegaVision)

Spectral RTI is emerging as an important tool for Digital Humanities and has become an essential tool for scholars working on ancient manuscripts, particularly for those working on recovering illegible texts and deciphering palimpsests. During this two-day workshop, participants will be introduced to the basic techniques, methods, and best practices for Spectral RTI, and will have the opportunity to produce images using Spectral RTI. The workshop will be led by Todd Hanneken and Ken Boydston, leaders in the practice of Spectral RTI. All necessary imaging equipment for the workshop will be provided.

As space in each workshop is limited to 20 participants, applicants must agree to participate fully in both days of the workshop. Applicants are asked to submit an explanation of their interest in the workshop, specify which iteration they wish to attend (British Library or UCL), and to describe any objects to which they have access and of which they are interested in producing images during the course of the workshop. To apply to participate in the workshop, please submit your application via Eventbrite by the deadline of 10 June 2019.

These workshops are co-sponsored by the British Library and the UCL Centre for Digital Humanities, and supported in part by a grant from the National Endowment for the Humanities.

For more information or questions, please contact Dr Christina Duffy (christina.duffy@bl.uk, British Library) or Dr Kathryn E. Piquette (k.piquette@ucl.ac.uk, UCL Centre for Digital Humanities). To register please use Eventbrite.
