Bartlett's prints take the sea as their subject. In Blue Foreshore he chooses to use a more abstract approach, focusing on the shapes and patterns he observes. Blue Foreshore captures the movement of the waves on the shore in the geometric patterns and swirls as well as the beautiful clear blue colour of the sea.
Etching and aquatint are both known as 'intaglio' printmaking processes in which designs are cut into metal plates by using different resistant grounds and acid. Ink sits in the acid etched cuts and is forced out by the pressure of a press to create the printed image on paper. Etching produces lines whereas aquatint produces areas of tone. The processes may be used in combination on the same plate and manipulated to give a subtle range of marks and effects with different qualities of line and tone.
