Our Mission:
Cultural Heritage Imaging (CHI) drives development and adoption of practical digital imaging and preservation solutions for people passionate about saving humanity’s treasures today, before they are lost.

Our vision at CHI is to democratize technology, empowering people all over the world to document their own cultural heritage, helping to preserve and protect it for future generations.

The technologies and principles that guide our work are leading to new and easy-to-learn imaging techniques that can be made available and accessible to people all over the world.

By providing tools, technology, and training, CHI drives the adoption of new practices by a broad constituency, from major art museums to remote archaeological sites to fields in the natural sciences.
