David Brewster taught Adamson the calotype process along with Adamson's brother John. Trained as a chemist, Adamson established a photography studio which the painter, D. O. Hill joined. Known as Hill & Adamson, the studio was in existence between 1843-47. Adamson's untimely death ended the successful partnership. In the short life of their studio, they produced close to 3000 images. Regarded as pioneers in photography, they explored the artistic elements of photography, particularly portraiture.
