Shortly after the dawn of photography, the unlikely partnership between the respected painter David Octavius Hill and the young engineer Robert Adamson produced some of the most important photographs in the history of the medium. During their brief but prolific association (1843-1848), Hill and Adamsom experimented with some of the earliest calotype processes, creating hundreds of portraits, staged dramatic photographs, and architectural and landscape images. The Getty Museum holds more than four hundred of their works, forty-seven of which are featured in this latest addition to the popular In Focus series. This collection of remarkable images also includes commentary on the plates, a chronology of the artists partnership, and an edited transcript of a colloquium on the artists.
