Brands: RTI Dome and Light Array outfitted by Cultural Heritage Imaging (CHI)
DSLR Camera: Canon Digital Camera EOS Mark III
Lens: Canon 24-70 mm F/2.8L
Capabilities: The dome measures 4.5 ft in diameter and features 45 halogen lights affixed at specific measureable angles along 4 tiers. Candidacy for optimal RTI under the dome corresponds to objects with maximum dimensions of 12 x 12 x 8 in. Alternative methods can be adopted for imaging of objects that exceed those measurements.
Practical use: Reflectance Transformation Imaging is a method of capturing how the surface of an object interacts with light. This digitization process yields interactive visualizations that allow users to manipulate the direction of virtual light sources. A user manual created by the Digital Imaging Lab outlines the process step by step and offers support.
