Reflectance Transformation Imaging (RTI) of Saw Marks on Bones

This study investigated whether RTI may be useful for preservation and analysis of saw marks on bones through a comparison of RTI photographs to traditional photographic counterparts. RTI was found to be excellent for visualizing tool mark on bones, though it was more successful in capturing shallow surface details versus deeper alterations. Time and file storage may be minor limitations, but overall RTI is relatively inexpensive, easy to perform, and effective for imaging alterations on bones.
