The Technical Development of Oil Painted Photographs on Canvas in the United Kingdom Between 1850 and 1890, with a Case Study of Paintings by Georg Koberwein from the Royal Collection.

Painting with oil over photographs on canvas was a widespread practice in the nineteenth century, mainly for the production of portraits and copies of oil paintings. It flourished in a context where both photographers and traditional painters were trying to innovate and adjust to new technological advances and demands of their time. However, despite the popularity of oil-painted photographs, they have not been the subject of substantial technical and historical study, which resulted in most of these photo-paintings not having been properly identified. Therefore, this research looks at the photographic processes used for printing on canvas in the UK between 1850 and 1890, knowledge of which is necessary for the identification of photo-paintings. It also looks at how the practice of the Austrian painter and photographer Georg Koberwein (1820–1876) fits within this context, including the examination of four paintings by the artist in the Royal Collection.
