AIC's 46th Annual Meeting

Reflectance Transformation Imaging (RTI), a computational photography technique, is a portable, low-cost imaging method used to create high-quality digital representations of an object’s surface. Using a basic digital photography setup, images are captured and then interactively re-lit and enhanced through open source software. Invented by Hewlett-Packard Labs and further developed by the nonprofit corporation Cultural Heritage Imaging (CHI), RTI has been applied by conservators to document and analyze tool marks and other evidence of manufacture and use; to clarify and record inscriptions; to accurately record surface condition; and to qualitatively assess surface change
over time.

Attendees will complete the course with all the fundamental materials needed to conduct highlight-based RTI in their studios with their own photography equipment, including written guides to both capture and processing, software and one set of 1" reflective spheres.

This course is intended for individuals with at least a general understanding of digital photography and digital image processing; they are not required to have previous experience with RTI, but are encouraged to review examples and background through the CHI website prior to attending.

Members of AIC's Conservators in Private Practice Group can register at the discounted price of $210.
