During COVID lockdown and after retiring from a 30 year career in the police, Douglas Ledingham discovered a neolithic cup-marked stone becoming involved in the Scottish Rock Art Project. Douglas has learned how to produce 3D photogrammetry models and also 3D modelling of Pictish stones. His interest has sparked a passion for discovering the past and producing 3D models. He wants to share his learning and enjoyment of these new skills with our u3a.
