Photogrammetry and reflectance transformation imaging (RTI) are techniques for creating interactive spatial images. We are using these techniques to create representations of Blackfoot cultural heritage, as well as in workshops and art-making.
Photogrammetry is a photographic process that creates an extremely dense and precisely textured 3D model.
RTI is a photographic method that captures a surface’s shape and color. The resulting digital file can be digitally interacted with as if with a raking light, revealing detailed surface information.
Cultural Heritage Imaging is a great resource for learning about photogrammetry and RTI. They offer free software for building and viewing RTI projects.
