In 1965, Morrison joined the staff at Duncan of Jordanstone College of Art, Dundee and settled in Montrose. He left the College in 1987 to paint full-time.
Whilst in Glasgow he painted several striking canvases of Glasgow tenements. Best known as a landscape painter, his main working areas are the lush farmland around his home in Angus and the rugged landscape of Assynt in Sutherland.
The Royal family own several Morrison paintings, as does J K Rowling.
