Reflectance Transformation Imaging (RTI) is a new imaging technique that creates hyper-realistic digital surrogates that are interactively controlled by the viewer. This new method is based upon the synthesis of multiple digital images of a subject in a fixed position collected from a fixed camera position. The technique involves the capture of multiple images with the subject and camera position fixed and the light source position varying. The series of images are lit from a point source of light that is at a constant radius from the subject, but relocated through a virtual hemisphere of positions.
