(active from 1843 circa to 1848 circa)
Among the greatest interpreters of the calotype are David Octavius Hill (Perth 1802 – Newington 1870) and the photographer/chemist Robert Adamson (Burnside 1821 – St. Andrew 1848), both from Edinburgh. Their collaboration began in 1843, when Hill was asked by the Free Church of Scotland to create an enormous picture that had to represent the portrait of the 470 people who had abandoned the Scottish Church. In order to execute this large commission, the camera seemed like the equipment best suited for the task. From that moment on, portraiture took the upper hand in their career. Each person portrayed by Hill and Adamson is shown in extremely natural poses. They look neither for detail nor perfection in detail, which is the main concern of the daguerreotype, but instead the effect that only paper negatives can give: a suggestion of chiaroscuro, a game of light and shadow, closer to drawing and painting.
