A couple of weeks ago Carla Schroer conducted a workshop for a selected group of members of the Western Association for Art Conservation (WAAC) and members of cultural institutions in the Portland, OR area. The workshop was conducted at the beautifully restored and technologically advanced White Stag building of the University of Oregon, Portland. The title of the workshop was Digital Imaging Techniques for Conservation & Education. The three hour workshop was divided in two main sessions. In the first session, Carla lecture, via presentations, on the development and implementation of Reflectance Transformation Imaging (RTI) in the conservation field and cultural heritage institutions.
Carla brought a small fossil with her to be photographed. She explained the minimum equipment requirements and recommendations for successful setups for different size and types of objects. Once all the mechanics where explained Carla, a volunteer from the group, and my self proceeded to capture the object with 24 images each with a different lighting position. She followed by explaining the postproduction steps to build the final RTI image as well as the use of available viewers for these images. She also demonstrated some of the computational enhancements that could be applied to the images and the amazing amount of information that can be obtained in this way. The day ended with a great Q&A session that really brought home many of the concepts that Carla had touch upon during the day finalizing a really informative workshop.
On a personal note I am very happy to have had the opportunity to assist Carla with the practical aspect of the workshop, but even more happy that Carla came to the meeting and that she was able to mingle and meet many of the members of this wonderful WAAC organization. Wishing a long lasting partnership and collaboration among the two institutions I remain thankful.
