Do you know the book 'Garden People' by Ursula Buchan? With the subtitle 'Valerie Finnis & the Golden Age of Gardening'.
Ref.: Thames and Hudson, London, 2007.
She took some 50.000 pictures in total, most of them with a Rolleiflex camera.
"Despite the growth in professional garden photography and advances in both techniques and technology, Valery is still acknowledged by modern practitioners of the art as one of the finest plant photographers that there has ever been, and a strong influence on those who came after her. She was notable for a 'natural' style, particularly evident in her collections of flowers, gathered from her garden in every season of the year."
Valerie had a weakness for outrageous hats, both wearing them herself and photographing others in them.
The person on the right is Miss Beatrix Havergal, founder of the Watterperry School for Horticulture. We see her here attacking a visitor desperately begging to spare his poor life. Yes, Miss Havergal was rather eccentric.
