Here’s an extended video version of my talk “Documentation Of Lithic Artifacts Using An Inexpensive Reflectance Transformation Imaging System”, originally presented at the 2015 Society For American Archaeology conference in San Francisco. It includes a few slides omitted from my original presentation due to time limitations, as well as a few more software demonstrations. Use the “full screen” button at lower right (shows up after the play button is pressed) for best viewing.
A PDF of the slides in my talk can be downloaded using this link.
