Virtual reconstruction of archaeological artifacts has been a challenge in archaeology. Common reconstruction methods include photography and 3D drawings of the objects from various perspectives. However, these methods are time consuming and often lack the depth perception needed. Reflectance Transformation Imaging (RTI) is a novel technique to overcome these obstacles [1], [2]. This easy and inexpensive technique produces high-resolution 3D images[3], enabling archaeologists to examine artifacts in fine details. RTI technique includes two methods: using a dome [4] or using highlights. In this work the dome method was employed for the first time in Turkey. We imaged various stone, metal, clay, and bone objects from different perspectives (LEDs in different positions and angles). Processing these LEDs images using the RTI builder program produces a single 3D image that combines all of the obtained images. Altering the light positions on the program allows for greater detail and increased depth perception. For example, by analyzing the RTI images of clay artifacts we could distinguish the fingerprints left by the people who made and used these objects. The RTI method has the potential to reveal new information about ancient societies.
