David Octavius Hill - Mrs. Logan and Two Unknown Women, Newhaven

In 1843 Hill and Robert Adamson formed a partnership and established a studio at Rock House, Calton Hill, Edinburgh, Scotland, where Adamson was in charge of photographing and the chemical processes and Hill was the artistic director overseeing costumes and arrangement of the sitters. This partnership lasted until the death of Adamson in 1848.

David Octavius Hill was a Scottish painter and photographer. He was a pioneer of photography in Scotland and is best known for his collaboration with Robert Adamson in which they produced some of the most important early photographs of Scotland.

In 1843, Hill was commissioned to paint a group portrait of the leaders of the Free Church of Scotland, which became known as the "Disruption Assembly" painting. He then decided to photograph the same people in order to have a more accurate representation of the individuals. This commission led him to take up photography and he teamed up with Robert Adamson, who was a master of the new collodion process. Together, they produced a large body of work that depicted the people and landscapes of Scotland during the mid-19th century. Their photographs are considered some of the most important early photographs of Scotland, and are widely recognized for their technical excellence and artistry.
