English: Rock House (centre) was the home in the 1840s of the scientist Robert Adamson, who formed a partnership with the artist David Octavius Hill with a view to exploiting Henry Fox Talbot's new calotype process of photography. Hill & Adamson began their collaboration by producing portraits of ministers of the new Free Church of Scotland, established after the Disruption of 1843. Over the next three years Adamson's knowledge of chemistry, combined with Hill's aesthetic sense, produced thousands of calotypes covering a range of subjects, from prominent Edinburgh citizens, soldiers and landmarks to family members and friends, and the distinctive fishermen and fishwives of the village of Newhaven to the north of Edinburgh. Many of their photographs were taken in the studio they set up in the garden of Rock House.
