An autochrome of two sisters, daughters of the photographer, together in a garden on a hot summer's day, taken by Etheldreda Janet Laing. The younger girl has fallen asleep in her sister's lap. In the summer of 1908 Laing took a series of autochrome portraits of her children in the garden of the family home, Bury Knowle. As a young woman Laing studied art in Cambridge and became an enthusiastic amateur photographer. The autochrome process was the first really practicable and commercially successful process for colour photography. Patented in 1904, it was invented by French film pioneer brothers Louis and Auguste Lumiere. Autochromes are transparent images on glass, similar to lantern slides.
