The Awakening ~ by Emma Barton (1872-1938), Carbon print, taken somewhere in 1903
Emma Barton’s photography was influenced by Old Master paintings, the Arts and Crafts movement and the Pre-Raphaelites, and she was also a pioneer of color photography using the Autochrome Lumière process.
The atmosphere of this tender portrait reminds me of this image of mother and child by Southworth & Hawes, see link here. Personally I prefer the latter image because it is more natural whereas the photo of Emma Barton is more stylized. The difference is also that this photo is about the awakening, while the other photo shows a child just fallen asleep.
