For the past 20 years, Sarah Adams has captured in oil the rugged features of the north coast of Cornwall where she lives. In this episode, she talks about the artistic journey she has made towards becoming a landscape painter, the extraordinary efforts she makes to explore the stacks, arches and caves that she depicts, her process involving detailed primary sketches and subsequent under-glazing and amplified colour, how she has noticed gradual changes in the coastline over the years and the threat of plastic waste to the coastal environment.
