Scottish Painter and Photographer, 1802-1870 was a founding member of the Royal Scottish Academy and its secretary for 40 years. In 1843 he enlisted the help of Robert Adamson (b. 1821, Berunside, Scot. January 1848, St. Andrews), a chemist experienced in photography, in photographing the delegates to the founding convention of the Free Church of Scotland. They used the calotype process, by which an image was developed from a paper negative. In these and other portraits they demonstrated a masterly sense of form and composition and a dramatic use of light and shade. Their five-year partnership resulted in some 3,000 photographs, including many views of Edinburgh and small fishing villages.
