Douglas Ledingham – A Journey Through Time
Douglas Ledingham gave a fascinating talk on using 3D photogrammetry to illustrate aspects of our physical heritage. He explained that he became interested in this technique after he came across a cupping stone in East Lothian. Cupping stones are a form of rock art dating from prehistoric times. They can be found throughout Scotland and the speaker has followed up his interest in helping to verify such stones, including in Aberdeenshire where he now lives. His expertise in 3D photogrammetry is being used to better understand Pictish stones and graveyard memorials. The technique produces 3D images that are able to enhance the artwork on a stone, and the software can be transferred to a 3D printer to produce accurate scale models. An excellent talk was enhanced by examples of his photography and several 3D models.
