Looking Over the Artist's Shoulder: Multi-Spectral Imaging the Segesser I Hide Painting Created between 1693 and 1730, the Segesser I hide painting portrays a punitive expedition comprising Pueblo Indian and Spanish troops against the Apache Indians. Now on display at the Palace of the Governors, the 18 ft. long bison hide painting is undergoing multispectral imaging to identify materials, changes over time and painting techniques. In order to image the huge architectural mural that is Segesser I, a computer controlled travelling imaging gantry table was designed and built. Called the “Franken-Camera”, it allows the painting to be imaged flat and with .001” positioning accuracy. It will take 3817 images to complete this project and create files totally more than 4 Terrabytes.
