She takes up photography at the relatively late age of 48, when she is given a camera as a present.Although her style is not widely appreciated in her own day, her work has had an impact on modern photographers, especially her closely cropped portraits.

Her house, Dimbola Lodge, on the Isle of Wight, is open to the public.
