Colour Photograph (Dufay Dioptichrome Process?) of a Woman in Profile, Probably by W. A. Casson, c.1910

The emulsion has shrunk and split, causing cracks and incorrect colour, a common fault with early examples of the Dufay process. A beautiful woman in an Edwardian dress, standing in profile. She is probably the same woman as in 23641, hence the attribution of the present photograph to Casson. He exhibited colour photographs (processes not specified), including a portrait of a woman, at the Royal Photographic Society exhibition in 1911.
