Joseph Mallord William Turner was perhaps the most prolific and innovative of all British artists to take inspiration from the landscape.
These works by JMW Turner, bequeathed to the Scottish National Gallery by the distinguished collector Henry Vaughan, span Turner's career, from his early topographical wash drawings to his atmospheric sketches of continental Europe in the 1830s and '40s.
Vaughan stipulated in his bequest that these delicate watercolours should be 'exhibited to the public all at one time, free of charge, during the month of January', and his wishes have been faithfully adhered to for over 100 years.
Scottish National Gallery, Edinburgh, to Tuesday 31 Jan.
