Training for Field Work

CHI offers training classes and workshops for conservators, archaeologists, museum curators, and others who want to learn how to use the low-cost, effective digital techniques in which CHI specializes.

Training class in RTI and conservation

Learn how Reflectance Transformation Imaging (RTI) can be used to create digital substitutions, or surrogates, that reveal object features that are difficult to discern even under direct physical examination.

Cultural Heritage Imaging (CHI) refines its best practices through rigorous field tests with real-world collaborators in the cultural heritage community. The interdisciplinary nature of CHI’s work makes productive efforts in the field an essential part of the CHI mission.

Art Conservation

Rock Art

Ancient thunderbird rock carving in Legend Rock, Wyoming

Paleolithic rock art is among the earliest surviving examples of humanity’s cultural heritage. To support research and documentation of this highly perishable form of cultural heritage, CHI has used RTI technology to record and study rock art from several time periods, in the field.

Coins being prepared for imaging study

Numismatic (coins) photographic documentation is challenging because of the characteristics of highly reflective metallic materials with a variety of delicate surface patinas and a fine-featured, low-relief morphology. Reflectance Transformation Imaging (RTI) offers a powerful method of documenting and communicating numismatic data.

forensic footprint study

For anyone involved in photographing and examining evidence, RTI can dramatically improve the visualization of textural data, including footwear, tire impressions, toolmarks, patent fingerprints, cadaver prints, indented writing, ink cross-overs, and obliterated serial numbers, to give just a few examples.
