This work records McLean’s attempt to make paintings in which the landscape itself played an active, creative role. He laid a 150-foot roll of sensitised paper on the seashore at Largiebeg on the east coast of the Isle of Arran, and intended to let the incoming tide mark the paper. However, the tide came in so quickly that the paper floated out to sea.
The paper is of a type used for reproducing architectural drawings, which changes colour when exposed to light (not water). But the location McLean chose was the sea, because in seascape paintings the sea is blue.
