How petroglyph images are recorded in the field is instrumental for analysis, archiving and publishing data. Being prepared to implement multiple advanced imaging techniques provides numerous advantages. Because lighting conditions, preservation and manufacturing techniques vary from one petroglyph locality to the next, having the flexibility to apply different imaging options as appropriate greatly facilitates data retrieval. Many archaeological projects require that the bulk of the image...
Contextualizing Petroglyphs: Reflectance Transformation Imaging (RTI) and Public Archaeology (2018)
The central question that drives our inquiry is: How can technology, specifically Reflectance Transformation Imaging (RTI), pair with material culture and archived/published oral tradition in order to enhance visitor experiences at a sacred American Indian site? Jeffers Petroglyphs is a Dakota site located in Comfrey, Minnesota with over 5,000 known petroglyphs, dating up to 7,000 years. Today, these petroglyphs hold spiritual and historical significance for the Dakota people, yet cannot be...
Documentation Of Lithic Artifacts Using An Inexpensive Reflectance Transformation Imaging System (2015)
Reflectance Transformation Imaging (RTI) creates a relightable virtual image of an artifact, allowing interactive manipulation of the light direction and light curve characteristics to bring out details difficult to impossible to see with the naked eye or in a photograph. One potential use of RTI is in the visual documentation of lithic artifacts, traditionally done using line drawings because of the difficulty in recording their features using still photographs. Techniques for enhancing lithic...
